Identification methods: 1.Signature based detection 2. Heuristic-based detection
Signature based detection: it's most common method to take down virus. This process, antivirus compares contents of the file to directory of virus signatures. Every virus program contains different malicious proggram. Firstly, antivirus collects odd proggram then create virus signature database.

Many viruses start as a single infection and through either mutation or refinements by other attackers, can grow into dozens of slightly different strains, called variants. Generic detection refers to the detection and removal of multiple threats using a single virus definition. [source:Wikipedia]
