The first computer virus was developed by a graduate programmer. This program has the ability to copy itself from one floppy disk to another. But this small deed caused many strains and has spawned many industries to pay millions.
As the students study in their biological books, these viruses are not able to replicate themselves but instead they need to attach themselves to an existing computer program. The categorization of these viruses is done in three parts based on the host they attack viz. Boot Sector Virus (BSV) [link widoczny dla zalogowanych], File Virus and Macro Virus.
That can be referred as the foe for your data that lies within your system and then overwrites your saved data and makes you feel the need of data recovery. BSV targets the boot loader program that is placed at the start of hard disk. Now if any of the storage media like floppy disk is put in the drive then it will become infected. These viruses can not be spread over the net as they are dependent on the physical transfer through the infected diskette.
Now the second type which is file virus attacks on the program files and attaches itself to them. To load the virus instructions first before the control is returned to the original program, the host program is modified. There are two options for these programs: first is that they get executed once and the second one is that affect each new program file that runs.
Macro Virus makes their target to the small programs of MS Office documents called macros. These programs are mostly written in language VBA for the customization of the software and the virus writers make this advantage to carry out their black art.
The ultimate loss is the data and the infection of your system. The life cycle of the virus goes on when you unintentionally send a memo as an e-mail attachment or pass the affected disk to other computer users. This is the way how the virus infection spreads.
Some if the viruses are too clever that they do not make clear any sign of the infection until it has had time to spread themselves. These occupy the disk space and may also slow your system apart from affecting the data.
The protection meant from the virus infection runs in many ways. These include ensuring not to boot from the affected drive and never to open an e-mail attachment without scanning by the anti-virus program. The base security measure would be to have an anti-virus program which is advanced along with its recent updates.
To get rid of the virus [link widoczny dla zalogowanych], usually formatting of the drive is performed but this costs them at that time when they realize that the data which is going to be lost in the mean time is of crucial importance. Well there is no need to worry at all as for that data; the help is there in the name of data recovery software.
These data recovery software analyze your hard drive to get the valuable data back even after the formatting. Handling with the data recovery need, when the virus attack is there is easy through these software.
Stellar Information Systems Ltd. is the data recovery company which specializes in providing the quality products for the data recovery. You can have these software for the operating systems like Windows, Linux, Novell [link widoczny dla zalogowanych], Macintosh and UNIX. These data recovery software use the most powerful algorithms for carrying out the task and ensure you a safe data recovery. They do not perform any write operation on the data and keep it intact.
