There literally hundreds of viruses circulating for personal computers and many anti-viral packages that claim to remove the code from your computer. Some viruses are polymorphic; that is, they change with each infection in an attempt to avoid detection by anti-virus programs. As quickly as someone writes an anti-virus program, someone else writes a new virus that hides more successfully than in the past.

Do to the harshness of some viruses; people have devised methods of detecting and removing them. The anti-viral programs will scan the entire hard drive looking for evidence that viruses may have infected it. These programs must be told very specifically what to look for on the hard drive. There are two main methods of detecting viruses on a computer. The first is to compare all of the viruses on the hard disk to known types o

Virus-specific detection and removal techniques required detailed analysis of each new virus as it is discovered. Computer virus experts must identify strange sequences of instructions that appear in the viral code but not in normal programs. These experts develop cures to remove these viruses from any infected hosts.
