Author: The Internet ha become mission critical for many institutions today, including large and small companies, universities, and government agencies. Many individuals also rely on the Internet for many of their professional, social, and personal activities. But behind all this utility and excitement, there is a dark side, a side where “bad guys” attempt to wreak havoc in our daily lives by damaging our Internet-connected computers; violating our privacy, and rendering inoperable the Internet services on which we depend [Skoudis 2006].
The field of network security is about how the bad guys can attack computer networks and about how we, soon-to-be experts in computer networking, can defend networks against those attacks, or better yet, design new architectures that are immune to such attacks in the first place. Given the frequency and variety of existing attacks as well as the threat of new and more destructive future attacks, network security has become a central topic in the field of computer networking in recent years. One of the features of this fourth edition of this textbook is that it brings network security issues to the forefront.
We’ll begin our foray into network security in this section, where we’ll briefly describe some of the more prevalent and damaging attacks in today’s Internet. Then, As we cover the various computer networking technologies.We’ll consider the various, security-related issues associated with those technologies and protocols armed with our newly acquired expertise in computer networking and Internet protocols, we’ll study in-depth how computer networks can be defended against attacks, or designed and operated to make such attacks impossible in the first place. Since we don’t yet have expertise in computer networking and Internet protocols, we’ll begin here by surveying some of today’s more prevalent security-related problems. So we begin here by simply asking, what can go wrong? How are computer networks vulnerable? What are some of the more prevalent types of attacks today? The bad guys can put malware into your host via the Internet. We attach devices to the Internet because we want to receive/send data from/to the Internet. This includes all kinds of good stuff, including Web pages, e-mail messages, MP3s, telephone calls, live video, search engine results, and so on. But, unfortunately, along with all that good stuff comes malicious stuff—collectively known as malware—that can also enter and infect our devices.
Once malware infects our device it can do all kinds of devious things, including deleting our files; installing spy ware that collects our private information, such as social security num-hers, passwords, and keystrokes, and then sends this (over the Internet, of course!) back to the bad guys. Our compromised host may also be enrolled in a network of thousands of similarly compromised devices, collectively known as a botnet, which the bad guys control and leverage for spam e-mail distribution or distributed denial-of-service attacks(soon to be discussed) against targeted hosts. Much of the malware out there today is self-replicating: once it infects one host, from that host it seeks entry into other hosts over the Internet, and from the newly infected hosts, it seeks entry into yet more hosts. In this manner, self-replicating malware can spread exponentially fast. For example, the number of devices infected by the 2003 Saphire/Slammer worm doubled every 8.5 seconds in the first few minutes after its outbreak, infecting more than 90 percent of vulnerable hosts within 10 minutes [Moore 2003). Malware can spread in the form of a virus, a worm, or a Trojan horse [Skoudis 2004]. Viruses are malware that require some form of user interaction to infect the user’s device. The classic example is an e-mail attachment containing malicious executable cods. If a user receives and opens such an attachment, the user inadvertently runs the malware on the device.

Why Backup?
Computers are becoming more and more important in people’s lives. They are the center of many crucial activities that people perform. Communications, finances, entertainment, news and more can be centered on your PC.
PCs are electronic and mechanical devices and they can fail. People can accidentally wipe out their own data and programs and malware can wreak havoc. The only real protection is extra copies provided by proper backup.
Backup Strategy
A backup system should provide for the ability to totally restore your system from a full wipe out. It should also make the process as painless, efficient and economical as possible. Data safety should be insured by protecting against harm and by providing high reliability data for restore. The backup system should be automated, unobtrusive and automated so that it always gets done.
Bare metal restore is best provided by a high speed backup to a an external drive using a program that is powerful and easy to use such as Acronis.
Safety is provided by having multiple copies of your data in different places. By having the data in different places, you insure that is something happens in one place the other place is not affected.
Your computer hard drive, a local external hard drive, a full backup on an external drive kept offsite and online backup provide a superior 4 levels of protection and is an ideal set up. Multiple sources insure that if 1 of the devices goes bad, you have others to cover.
There should be a daily incremental backup to a local drive, a periodic backup of the full system to an external drive which will be taken elsewhere and online backup for important data and file.
Primary Role of Online Backup
Online backup is really not meant for full system backup or even very large file backup. It’s simply too slow to do this job. A 1 GB backup will take about an hour on a fast connection. Online storage is also expensive even though it may be cost effective for some business purposes.
Online backup provided by a good company is safe and redundant in itself. The online backup companies store the data on Raid 6 type systems where the data is stored on multiple hard drives at the same time so that a few of them would have to fail at the same time to cause any loss of data (a very highly unlikely event). Additionally, they would have mirrored servers at another site so that even if 1 site went down the other would still be up.
It is also good for those who travel and can’t always get to a backup drive since all you need to backup is an Internet connection.
This means that the files that are really important and are not system files should be backed up using online backups.
Online backup also has a new feature in that it can backup contacts for iPhones and Blackberry phones.
Online Backup Features
The best online backup programs will have the following features:
easy backup and restore
background or scheduled backup
multiple revisions of the same file is a bonus
encryption for safety
works automatically and is reliable
Compare offerings
There are many online backup programs. Some of the most famous are Carbonite, Mozy, iDrive and SOS.
Compare reviews to find which one is best for you. Also search for negative reports. The reviews don’t always tell the whole story.
Summary
Online backup is an important part the overall backup that you do to keep your computer safe and humming along.

The pleasure of using the Internet can quickly turn into a less than desirable experience when your surfing brings you up against adware and/or spyware. Infections from these small software programs can wreak havoc on your computer for a long time, so it is important to make sure that your computer is protected from these types of programs.
AdWare Alert is an adware protection software program that not only removes existing adware infections, it stops future infestations from happening as well.
Malware, which is short for malicious software, is engineered to steal the identities of website visitors, track their every move while they are surfing online, and in the worst case scenario, steal credit card and bank account information. Malware also increases that irritating spam that we all receive in our email inboxes by stealing our email addresses.
There are many types of malware and they can originate from many sources. Its devious purpose is to silently keep watch on your computer, dig deeply into your computer system, and pass data back to the original writer of the program. Obviously, the programmers who write malware do not have the best interests of the average computer user in mind. Malware is exactly what the name implies, malicious software designed to both damage a user’s computer and steal personal information.
Adware is similar to spyware, but in most cases it installs a small bit of code onto your computer without your knowledge. One of the most obvious symptoms is that your computer will frequently show pop-up windows that contain advertisements. In the worst of circumstances, an adware infection can make it almost impossible to surf the web.
Another harmful thing that malware can do is to install small, unwanted spyware programs that ride “piggyback” on the malware program or even a music file you could have downloaded from the web.Adware Alert is a straight-forward program to install and use and is also very reasonably priced. Even beginner computer users should have no problem installing and setting up Adware Alert. Essentially, AdWare Alert hunts down spyware and adware on your computer, targets the offending files or programs, and then removes them. It also stops future attempts by malicious Internet sites, concealed click-throughs, pop-ups and pop-unders from installing malicious software onto your computer. It will alert you when malware attempts to access your system and blocks the offending program and any pop-ups too. This is one case where the old saying “If it ain’t broke, don’t fix it” definitely does not apply.
In the case of adware and spyware, if your computer is not properly protected, it is not a question of whether your computer will get infected, it’s a question of when. Installing a program like Adware Alert can permanently stop malicious software in its tracks so it is definitely a worthwhile investment.
Charles has many years of experience in the adware/spyware software field. His reviews of several adware and spyware protection software programs, including Adware Alert, can be found at http://www.adwarespywarereviews.com. You can easily protect your computer from harmful adware and spyware by installing a protection program like Adware Alert.

WoW Hunter Guide
Choosing the right class to level up Warcraft with can leave you with a bit of a dilemma. Why not try the Hunter; this class has a lot to offer. Please read on.
This Hunter Guide has been designed to help you to do well as a Hunter, with any of the following races: Blood Elf, Draenei, Dwarf, Night Elf, Orc, Tauren or Troll.
With the skill to track down foe and kill them from a distance with their excellent weapons skills the Hunter is a formidable enemy for other class characters.
The ability to use range attacks upon the opposition is very advantageous to this Warcraft class as it significantly reduces the risk of injury. Furthermore the pet option makes sure that the majority of the close in fighting with enemies is conducted by the pet, leaving the hunter to wreak havoc from a distance.
As with all other character classes you will have the option to select from any of the professions. It is worth noting however that not all roles are ideal for the Hunter’s natural abilities. The best ones are Leatherworking and Skinning as you will be able to make your own protective armor, followed by Skinning and Mining, as you will be given the chance to make money from the sale of the skins and metal ores. Herbalism is also a good profession as this will allow you to learn how to make your own healing potions.
Initially your weapon of mass destruction is a rudimentary bow and arrow. I don’t think World of Warcraft domination is quite the aim yet! As you level up and finish tasks your personal arsenal of weapons will be much better. Your health points and experience points will also rise, making you a far more formidable hunter.
The secret to succeeding with the Hunter is to ensure your Mana levels are kept high, use your pet to undertake any Melee combat, only carry out combat from a safe distance, using your auto shot skill for the best results. If you stick to these basics where ever possible you will realise that the Hunter is probably one of the easiest WoW classes to level up with.

You have put hours into call of duty, you have defeated the bad guys and reeked havoc on unsuspecting newbies. It is a great feeling but what feels even better is knowing that the world can see what you have done and you can compare yourself against those very newbies and the most powerful and experienced players out there. Tracking your stats and the stats of your friends brings an entirely new element to the game. It is no longer just about what happens in one match or one day but rather what happens throughout your playing time on COD, plus it fulfills a bit of the voyeuristic tendencies of the human race. You know you want to see what your friends are doing in their game, go ahead, it is okay to admit it.
Until a few months ago you had to go searching for your stats and matching them up against other players was impossible, but in November of 2008 the Call of Duty team revealed a stats site that enabled players to check their stats, compare them against their friends and the worldwide community and see where they sat in the field of Call of Duty players. You have to set up your stats account before you can go comparing yourself to other players,but it is really easy to do.
You basically need to link your COD account to the stats site and the Call of Duty website directly for all of the information to be loaded. When you are in multiplayer mode all you need to do is choose Xbox Live and enter your “barracks”. Once in your barracks you will see the “web stats” option. Each person’s web stats have a personal code that identifies you as a player. Write down your number and head over to CallofDuty.com. If you are a serious Call of Duty player odds are you have visited the site before. Log in to your account or create one if you have never been to the site before. Registering for an account is like registering for an account on any other forum or site put in your information and call it a day.
Once you are in your account you need to enter the “my account” tab. Once in the tab you will see a “link account” tab. Click that tab and pick your platform (PS3 or Xbox 360). You will be asked for your gamer tag or ID and the web stats code that you grabbed out of your barracks. Once you’ve done all that and confirmed the information is entered you can head back to your profile on the site and select the “COD WW DOSSIER”.Your stats will appear.
From now on you can track what is going on with your own stats and the stats of others who have linked their account. Feel free to browse around and check out all the features the COD team has really outdone themselves on the stats tracking site and it makes the entire game a whole lot more fun.

The consumer is the ultimate sucker. Who at the end of the day does not like free stuff? On the internet freeware is oft preferred by budget conscious users and these users often end being sitting ducks for spyware removal. Spyware basically latches onto your system and as its name suggests ‘spies’ on you while you surf the internet. Your usage patterns are useful to market researchers and their ilk. Apart from slowing your system down and affecting your system performance spyware also presents a real danger as some spyware are capable of transmitting your personal data to unscrupulous elements.
There is also the irritation factor as spyware can result in advertisements popping up all the time. These can be quite frustrating while one is trying to get some work done. Real problems can kick in with regard to spyware as spyware on your system can be responsible for start up issues as well as shutdown issues. Very often you will be redirected to another website without your ever wanting to go there. Your browser settings can change without your doing anything. Spyware can do all this and much more without your even being aware of its presence. Spyware is extremely surreptitious in its behavior.
There is really a genuine case for spyware removal as pop ads and annoying spyware can wreak havoc when you are trying to work. It is really important to look at spyware removal options carefully. There are several companies that offer antispyware software and some of this spyware removal software is even free. However, it is important to understand that even after having installed a good quality anti spyware software you cannot rest easy. The spyware removal software needs to be updated constantly and at regular intervals in order for it to be effective. New threats emerge on a daily basis and I personally feel that it is difficult for individual users to be completely on top of all spyware removal software updates that are made available by manufacturers. Here, the role of a tech support company becomes quite invaluable. Due to the fact that this their main line of business, they are able to inform and update their customers of potential threats within hours of its discovery.

Moreover, it becomes their responsibility, once you have them on board to handle all updates and spyware removal requirements, if any.
It has to be remembered that there in no one software package for spyware removal that will cover all spyware. No anti-spyware package can guarantee a 100% coverage. Hence, often there can be data loss even with ant-spyware software installed. Tech support companies can move fast to retrieve data for you and have you back in business in no time.
We know for a fact that Spyware can be anything from annoying to downright dangerous. Not something anybody would want surreptitiously residing on their system. Nor would anybody like spyware secretly pass on their personal data to unscrupulous marketers. The question really is what method that most home users and small businesses are going to adopt to get rid of them. My experience and common sense says leave it to the spyware removal experts. Once you have spyware removal experts on board, you can rest easy and concentrate on your core business.

You might bask in the comfort of warm indoor climate for 365 days when you say ‘I do’ – to cavity insulation process. Yes, actually your home including you can remain unaffected and can be wrapped in the comfortable blanket of warmth while it is chilling cold wind is blowing in winter and scorching heat is burning all in the summer. And the answer is cavity wall insulation. To be simply put, cavity wall insulation implies filling up spaces between two layers of brick walls with appropriate materials that negates heat flow. Just as benefits of wall insulation are being widely spread and felt throughout UK, installing this insulation system to houses have taken a form of norm.
It has been noted at the end of various insulation related studies that about one third of the heat is likely to be escaped from buildings when that have porous brick walls. More so if your building was constructed after 1930, those brick walls will contain spaces between them for air passage. Though, such building designs were thought as comfort friendly and advantageous in several ways, in those days, but, nowadays, it can be a threat to drastic climate change.
To be precise, this cavity wall building designs pose threat to the earth by deteriorating greenhouse effects and intensifying global warming hazards. You might be wondering how come your brick walls could be so menacing to environment? This is because, the heat lost through your brick walls you want to compensate through using heating equipment is operated by burning fossil fuels. More you burn this energy to use heating, more carbon dioxide is emitting in the environment leafing to havoc greenhouse effects. Around 1 tonne of carbon dioxide is being wasted through heating use in a year.
Luckily, we have this eco-friendly and pocket friendly solution to reduce wastage. It is none other than cavity wall insulation. UK government has altered expensive installation process much more affordable by offering cavity insulation grants. Cavity insulation grants slashes costs of installing cavity wall insulation either partially or fully, depending upon nature of property, property location, household income details, benefits entitled to homeowners etc.
Jack William is an article author, who brings the information about cavity insulation and cavity wall insulation through articles, news, press release and blog. For more details visit our home insulation grants website. http://www.homeenergysaver.co.uk/

It happens to the best of us; from time to time we lose data when a computer crashes or freezes, a hard drive becomes lost or corrupted, or a server goes down.
There can be many reasons for this – a power failure or bugs in the software; even criminal activity such as hacking or the propagation of viruses and other malware. Human error, such as accidental deletion of data can also wreak havoc. Studies have shown that around three quarters of all incidences of data loss are due to either human error or hardware failure.
Whatever the reason, when this happens, it is important to try and mount a data recovery operation. Data recovery is a process by which information is salvaged from secondary storage media that cannot be accessed by normal means.
Most forms of data recovery are based on a failure of the computer’s operating system and the solution is relatively simple – gain access to the system and copy the data that is required to another disk. Dealing with a failure of the hard disk itself is more complex and an attempt to recover the data may involve repairing the file system, or using techniques ranging from software-based recovery of corrupted data to replacing a damaged disk.
Most people lack the detailed technical knowledge that is required to perform all but the most basic data recovery, and rely on professional services offered by a number of companies. When doing so they want to know, above all, that those services will be reliable.
A good data recovery company will be well established with a list of testimonials from satisfied clients (particularly well known companies, academic experts and public bodies) and have a solid track record, although one should be wary of any that offer a 100 per cent success rate – no reputable professional can guarantee to recover all data every single time.
They will also offer a variety of services at different costs, again, depending on the form of the data loss. Some losses can be dealt with by the user, with a little advice, and the best companies provide this advice free of charge.
Furthermore, a good company will always be striving to improve its data recovery rates. The best now run research and development programmes, in conjunction with universities and IT companies, to increase their knowledge of how computer hardware and software can go wrong, and to minimise the chances of data loss occurring in the future.

Article Source: Anti Virus Software Review- Interrelated Knowledge Base Review About Anti Virus Software
In this time of looming economic recession, companies are advised to exercise immense caution when dismissing who have access to valuable company information. In McAfee’s 2009 findings, security experts warned that the global recession could place vital company information at greater risk than ever. Employees that are laid off are likely to steal valuable company information when given the opportunity, especially when it may help them secure positions with their future employers.
In the first such case brought before the courts of Singapore last year in 2008, seven ex-Citibank employees were sued with breaching client confidentiality when they moved over to UBS and took along sensitive customer information with them. Eventually, the Singapore government charged these seven under its Computer Misuse and Banking Acts when an email containing personal data that was misappropriated surfaced.
In an annual survey conducted at Infosecurity 2008 – Europe’s largest IT security event, 88% of IT administrators indicated that, if laid off tomorrow, they would steal valuable and sensitive company information including CEO’s passwords, customer databases, R&D plans, financial reports, and company’s list of passwords to unlock access to most of the information on the company’s network.
“Companies in Singapore are still not aware that when employees are told to leave the company, they often still have access to valuable and sensitive information using their passwords. This means they have the opportunity to vindictively steal data for competitive gains or even maliciously delete data to wreck havoc on your operations”, says Felix Chang – managing director of Adroit Data Recovery Centre, a company that also specializes in computer forensics.
Dismissed employees are just one side of the story. During times of economic downturn, companies also have to contend with partners and directors who resign or leave due to differences or board conflicts. Such scenarios present the perfect opportunity for data theft and sabotage. The departing party could very well steal the entire customer database, or even delete entire blocks of data to wreck havoc as a parting gift. In this digital age, all it takes is one click of a button to do destroy years of valuable information, as opposed to the classic method of manually burning papers and files.
With more instances of IT data theft, firms specializing in computer forensic services such as investigation of data theft and recovering deleted data are highly in demand. Companies such as Adroit Data Recovery Centre (ADRC) offers specialized techniques to uncover evidences related to data theft, or intentional deletion of sensitive or confidential information.
In the event that you suspect potential data theft or malicious data deletion, companies are advised NOT to do anything to the suspected hardware, and immediately contact a computer forensics specialist for assistance. Here are some golden rules that companies should observe:
• Do not power on the computer
This will change the last boot up time, which may result in evidence loss. Moreover, many items in the cache may be eliminated.
• Do not modify files or even browse through them
Although the action may seem harmless, you are actually changing the timestamp of the files as you browse through them, resulting in evidence loss.
• Contact a computer forensics specialist
Without following proper procedures, evidences acquired may not be permissible in Court. It is therefore important to ensure that forensic investigation is carried out by forensic specialists with proper training and experience.

If there’s anything no computer user wants, it is a computer clogged with adware and spyware. These malicious marauders of your computer cache can originate anywhere on the net. They can enter your PC through an email, or a file you should not have downloaded, or when you land on a malicious website. But no matter where they come from, adware and spyware waste no time beginning to slow down your computer. Even worse, they may email your personal financial information for criminal use, or they may open the door for even more malicious software to cause your computer havoc. You simply have to keep a good remedy on hand to remove both kinds of malicious software, and this removal methods needs to protect you 24/7/365.
There are three key ways that an effective adware or spyware removal program will operate on your PC. They may scan everything you view on the net. This kind of software needs to use minimal memory and it needs to be on at all times. If you have to manually scan your hard drive every time you download something from the net?and nobody can?eventually you will let something slip through. The programs that protect your computer have to work 24/7.
Second, effective adware and spyware removal programs have to be capable of digging deep into your files. If adware or spyware already infects your PC, they could lurk almost anywhere. You may have trouble finding them, but they do not have trouble slowing your computer down. A good removal program scans every single file on your PC accurately. It makes use of the latest definitions, updated once a week, and it doesn’t let anything slip past it. An incomplete scan, or an out-of-date definition simply won’t do you any good.
The third and final way you can recognize useful adware and spyware removal software is filtering. These programs use filters and definitions to recognize harmful sites before you click on them. They will tell you to halt before you visit these malicious websites or, worse, open malicious files. Integrated into your browser, these software removal options tell you whenever you have stumbled onto a site other users have blacklisted. By identifying potentially harmful sites and files, effective and protective software keeps malicious files from ever infecting your PC.
Good anti-adware and anti-spyware programs do many things for you that help protect your computer against harm. These programs will set up a defensive perimeter around your files to make sure nothing ever sneaks in to cause your computer problems. Guarding your files, warning you about suspicious sites, and updating themselves, these programs help keep your computer healthy and keep it virus and spyware free.

Whether it’s a notebook or desktop unit, there’s probably a computer in nearly every household. PC’s have become essential equipment in our daily life. We use them at the office, in college, for play and even more. Because of the computer’s prominence in our life, keeping it in peak operating capacity is paramount. But with daily use, our PCs tend to slow down and can even stop working. The degredation in performance over time can be for several reasons.
The registry keeps the software and hardware values for everything in the PC and everything connected to it. After awhile, orphaned entries aggregate in the registry. The registry needs to be cleaned so it can better perform its job. Lots ofregistry cleaners that are available say they will clear up your registry and make it run better, but, many make false claims and could cause your computer and installed software and components connect to it to stop running. Having a high-quality registry cleaner is essential to keep your PC’s performance at it’s peak.
The spyware and viruses could also be one of the reasons of a slow PC XP. Once surfing the web, you will eventually encounter viruses and spywares that would infect your PC. Staying out of the internet is not an option instead, you have to make sure that your computer is installed with a virus or spyware scanner in order to prevent any virus infection.
These spyware/virus scanner will clean and delete all these harmful viruses that could cause havoc to your computer’s entire performance. Do not settle for any substandard anti-spyware as this won’t help you in increasing your computer’s speed. What you need is a good quality antivirus that can do great wonders in your PC. This computer trouble must be immediately solved as this could not only slow PC XP but also put your computer to a complete halt.
Lastly, your PC likely needs more RAM. RAM is the key hardware component that helps PCs run more reliably and faster. typically, The basic computer with the XP operating system (OS) came with 256MB of RAM and Vista 1GB. These operating systems need double those amounts to run halfway efficiently.
But doubling the amount of RAM that came in retail PCs is usually not enough if you have multiple software modules running at once. The amount of added RAM should be at least 1GB for XP and 2GB for Vista. PCs with those OS installed could even benefit much more with 3GB of RAM if the PC will take it. Tripling a computer’s RAM make your PC act like a brand new machine and let it handle multiple tasks at once without bogging down.
The points above above are only the likeliest causes of a slow, inefficient PC. There lots more thing that can cause a PC to poorly run. The three outlined above, a clunked-up registry, viruse infection, and the need for more RAM are just the top three problems PC users might encounter.

Don’t let your PC turn into a pumpkin!
We’re all rightly concerned about viruses, trojans, rootkits and spyware. That’s why we spend so much time worrying about which anti-virus software is the best, and which spyware blocker is going to save us from imminent invasion! But how much attention do we really pay to Backup? To many of us it’s just an afterthought, if that. It’s a process that can be easily automated but a huge percentage of computer users fail to backup their precious data regularly. Now is the time to take action.
Develop a data recovery plan
You’ll be mighty glad you have an up-to-date backup of all your important files in a safe place should the worst happen and a virus does break through your defences and plays havoc with your hard drive! Or worse yet, if some light-fingered individual makes off with your laptop.
Important files to back up include documents, photos, and of course your I-tunes collection! It’s worth taking a little time to do some basic housekeeping and identify those files it would kill you to lose. They may be deeply personal, irreplaceable and/or critical to your business or profession. But it doesn’t stop there. What about your contacts list? Your mailing list? Your invoices and online shopping receipts?
Paperless billing is commonplace for utility providers, mobile phone statements, and so on. It’s easy to let those bills languish in a folder in your email programme, or on your desktop. But if you lose those records and need new copies your provider may charge you for them.
Backup your critical data every day
You should aim to backup your critical data every day. Whatever operating system you are using, XP, Vista, Mac, or Linux, it’s not that complicated to do. If your computer is less than five years old it should have some basic software to help you. In Vista it’s the Backup and Restore Centre. Find it and use it. It will at least give you the option to back everything up to a partitioned section on your hard disk, but a small external hard drive may be a better solution.
Your important, critical files may not actually amount to more than a few gigabytes. You could probably store them all on a decent memory stick. But memory sticks are really only to be used as a temporary storage solution. And heaven forefend you should lose the stick!
Most memory is taken up by the system files, i.e. the programs and OS (Operating System) for your computer, and usually you’ll have the system files already on CD so you shouldn’t need to back these up seperately. That said, it is quite possible to completely back EVERYTHING up if you have the storage capacity, which might be a good idea if a day of reloading the OS and essential software fills you with dread!
Identify your critical files and group them together.
Start by identifying your critical files and group them together, in their various subfolders of course, in one folder called ‘The Crucial Stuff’, or some such thing. That way it’s easy to simply drag that folder over to your external hard drive, or better still set things up to happen automatically.
Just a quick note to mention that you may have to disarm your firewall or antivirus software during this process – certainly during the first time you create a disc image. And the first time can take a lo-o-ong time! After that it’s usually a breeze because your software only updates files that have been changed since the last time.
If you’re running any kind of business you may need to go through this whole process several times a day. It’s easy and convenient to automate the process with the right software.
A good online backup service may well be more time and cost-effective, and you can use it in addition to your physical storage to provide an extra layer of protection and flexibility.
Backup Software
Your proprietory data backup and restore software will do the job, so don’t think you have to invest in additional software.
However, if you want something a little more sophisticated there are several good products worth a look. You’ll find some suggestions on my website, listed below.
Beware of over reliance on any one method
Don’t just rely on one storage method. As we already mentioned memory sticks are great for temporary storage, transporting files and so on, but they are easily misplaced or damaged. You should also consider backing-up to another hard drive, zip drive, or server and possibly using an online storage service if your budget will allow. When backing up to memory sticks or cards, zip drives, CD, DVD or tape storage media, make sure they’re kept in a safe and secure place, preferably away from your computer. They may hold detailed information about you and your clients which could be damaging in the wrong hands.
Apart from guarding against the impact of hackers, viruses, malicious software, and accidental data removal, a realistic PC backup plan can help protect you if your PC is stolen, or damaged in a fire or flood. Without wishing to sound like your grandmother, plan for the worst and hope for the best!

With a host of virus, mal-ware and spy-ware affecting computer systems worldwide, anti-virus tools are a critical component for PC users today. A computer virus attacks systems, affecting system performance, breaches security mechanisms and can wreck havoc on not only computers but entire networks. They damage files, applications and operating systems. Before the Internet arrived, computer viruses were spread through use of affected floppy disks. Now they can be spread through emails, documents or simply through networks. The nature of infection that they cause varies, depending on its nature.
Computer viruses can be classified into three main categories – virus that affects the boot sector of a computer, viruses that spread through macros and those that infect files. However, viruses are not the only ones affecting computer systems. There are other applications that can cause considerable damage. Examples include worms, adware, spyware, dialers, Trojans, etc.
They are executables that affect your system performance, can collect sensitive data and cause monetary damage or reputation loss.
Antivirus software helps to identify and remove all malicious applications including but not limited to viruses. They use scanning engines that can identify viruses by identifying the unique string of bytes that make up their composition. Most antivirus tools also study patterns to compare them with known traits of viruses. In case of infections, they are able to repair the files and in cases where repair is not feasible, they can quarantine the files or offer the option to delete the infected files from the system.
Your chosen antivirus solution should be able to offer you protection, at the minimum, from viruses that affect the boot sector, macro viruses, Trojans, worms and viruses that affect files. The other factors that might influence your decision of an antivirus solution are the speed and accuracy of the application and the usability.
These differ widely amongst vendors and you can do a feature by feature comparison before deciding on the application.
In the end, do remember that it pays to keep your antivirus software updated. With each passing day, more viruses are being created and released onto the computer networks. Most antivirus application developers keep researching and updating their application with the release of any known new virus or malware. Antivirus applications offer automatic updates or prompts whenever a new patch is available. It is advisable to avail the menu based definition updates or to opt-in for the updates whenever prompted to do so. Being on the safe side helps and it does when it concerns critical data that rests on your computer systems.
There are many antivirus software makers on the internet, so it is best to use one you can trust, consult the expertise at k7-computing.com before purchasing and they will direct you to a trustworthy, recommended product which suits your needs and price!
