Full Form Of Computer VIRUS: Vital Information Resources Under Seize. 

A computer virus is a piece of code that is loaded onto your computer or laptop or android without your knowledge and run against your clearance. The virus has a property to replicate itself and spread itself from one device to another device like a computer to another computer or an android to another android. It can affect the data files, boot sector of hard drive, disable antivirus or firewall to steal private data, corrupt system files, etc.

Computer Viruses are human-made programs generally write to corrupt a database, hack system or access private information to display political and humorous messages on the user's screen.

What Is Virus Signature?

In the antivirus world, a signature is an algorithm or hash (a number obtained from a string of text) that uniquely identifies a particular virus. Depending on the type of scanner being used, it may be a static hash which, in its simplest form, is a calculated numerical value of a snippet of code unique to the virus. Or, less commonly, the algorithm may be behavior-based, i.e. if this file tries to do X, Y, Z, flag it as suspicious and prompt the user for a decision. Depending on the antivirus vendor, a signature may be referred to as a signature, a definition file.

A single signature may be consistent with a majority of viruses. It gives permission to the scanner to detect a new virus it has never even seen before. This ability is commonly referred to as generic detection. A generic detection is less likely to be effective against completely new viruses and more effective at detecting new viruses of an already known virus family. Virus Family is a collection of viruses that share many of the same features and some of the same code. The ability to detect generically is most important, given that most scanners now include in 250000+ signatures and the number of new viruses being discovered continues to increase rapidly year after year.
