What is an Heuristic computer virus?

A heuristic computer virus is a virus/program that is capable of learning while running in parallel with other computer systems on a system which it is on. For example having really good anti virus detection software running along with say five or six different other programme's virus can learn passWords usernames. It can also run in parallel to systems that are heavily coded.Learning enough about the programme's codes until it can break through them.This virus can also take control of computer system's example from one that i know of is a heuristic virus hacking its way onto one of my friends computers.And in roughly one and a half weeks had all of his data files etc at its use and sent them to some place over seas.

There is currently only one way to get rid of a heuristic computer virus.And it is by purging everything that you have on your computer and i mean everything.But make sure you have back ups of all your computer data before doing so or before you happened to get the virus.
