Malware is an unauthorized program which contains harmful bugs and as a consequence people loose data, the bank accounts are hacked and other important information are collected, with the help of these malicious software.Malware is also known as a virus when it is channelized by a worm or Trojan horse. The malicious functions of these viruses are attacking the registry, blocking the functions of the programs and may be crash the system completely. It is very vital for the users to know the symptoms of a malware affected system. Many software are available to heal the computer from such attacks
To know how serious the malware is, one should understand the pattern in which it contaminates. Malware comes in a particular software and spreads each time during its execution There are different ways in which your system can be affected by a malware such as internet, outside devices, using of unauthorized software, etc. You should know the corrective measures.

The Linux operating system, an Open Source flag bearer is getting more and more popular because of a wide array of applications like Office suite, Drawing applications and much more. We don’t have to install additional software to do the daily Office work, DTP (Desktop Publishing), Technical Drawings etc. In other words, we can customize the operating system options at the time of install as per our preference.
The Ext3 is a popular file system used with the Linux operating system. We generally face data loss in Linux due to system files corruption, user error, or malicious software. We generally loose data in multi user environment in Linux where the files generally get deleted to make disk space or increase disk performance.
We can not recover files manually from an Ext3 file system based Linux hard drive. For ensuring that Ext3 could securely resume unlink after the crash, it zeros out block pointers in inode. Then only option you have is to “grep” for the parts of file, which have been removed.
Grep is command line based text search tool in Linux operating system. It searches for the files or standard inputs globally for the lines matching to given expression and retrieves them.
However, it is not essentially true that all files still remain there. This is less probable, since files have to be retrieved from the journal. On top of that, Meta data of file system is less logically related to the real data so that complex algorithms are required to find them back.
Every time the file is accessed, the Access Time gets changed and the inode is written to the hard drive with 32 other indoes, which reside in the same block. When this happens, copy of that particular block is written to journal. Thus, if your volume is not so large, and if you have recently accessed the files, which you wish to recover, you may be able to retrieve the block pointers from journal.
Although, this method works in a number of data loss situations, but can not guarantee full recovery in all possible scenarios of data loss in Ext3 file system. This tool comes with some limitations like:
It can recover only recently deleted files. If you have mounted the file system after data loss, it will not work.
If the file system is corrupted or there is any other issue with hard drive data structure, you will not get desired results.
It can not recover larger files.
Unfortunately, in all above situations, grep can not perform Linux data recovery and thus you need to find a third party Linux recovery software to get your data back.
Linux recovery software are sophisticated tools, which are designed to systematically scan you entire hard drive and extract all data from it. Linux data recovery software are generally very easy to use and thus not demand any sound or prior technical knowledge.
Stellar Phoenix Data Recovery Linux is the best ever Linux recovery tool and offers comprehensive Linux recovery, it supports all Linux file systems including Ext2, Ext3 and ReiserFS. With its intuitive user interface, we can have trouble free Linux data recovery for all Linux operating system distributions.

During POST or Power On Self Test, computer BIOS attempts to get information regarding all of the devices attached to your computer system. After examining the processor and primary memory (RAM), it checks for the devices like hard drive, CD ROM etc and shows them with messages on screen like ‘Found Primary Master’ and ‘detecting IDE drives’ etc.
-> POST (Power On Self Test) is the first thing done by BIOS when your computer first boots up. POST is an in-built diagnostic program, which examines the hardware of your computer system to make sure that everything is available and working properly.
Many times, the BIOS of your computer just declines to recognize the hard drive, basically makes it unusable- there is no way in which your operating system will recognize the hard drive if BIOS can not. Let’s observe why all this happens.
The most frequent reason of this problem is a badly connected or loose data cable. You should first ensure that data cable is properly plugged in, both into the motherboard as well as the hard drive.
The same thing goes for the power cable, so you should check it as well. You should also make sure that red lines on data cable and the power cable are contiguous to one another.
Once you have ruled out the cable problems, you need to check out the jumper settings on hard drives. If two hard drives are attached to a port, ensure that one is set as masters and other as slave.
Next, ensure that the hard drive controllers on motherboard are not disabled. These hard drive controllers control the IDE devices and without them BIOS could not detect the hard drives.
If any of the above mentioned methods does not work, you need to search for a data recovery expert to cure your hard drive. It seems that hard drive has some internal problems, which can not be cured without opening it. And you are not recommended to open your hard drive at your own.
Data recovery experts are highly qualified and trained professionals, who know all ins and outs of the hard drive and are able to fix most of the physical hard drive problems. To ensure absolute and safe data recovery, always go for the experienced and reliable data recovery company.
Stellar Information Systems Limited is the most trustworthy and leading data Recovery Company, having more than 15 years of rich experience. Stellar’s personalized data recovery services is offered by highly trained data recovery specialists through Class 100 Clean Rooms.
