History
Most of the computer viruses written in the early and mid 1980s were limited to self-reproduction and had no specific damage routine built into the code. That changed when more and more programmers became acquainted with virus programming and created viruses that manipulated or even destroyed data on infected computers.
There are competing claims for the innovator of the first antivirus product. Possibly the first publicly documented removal of a computer virus in the wild was performed by Bernd Fix in 1987. There were also two antivirus applications for the Atari ST platform developed in 1987. The first one was G Data and second was UVK 2000.
Fred Cohen, who published one of the first academic papers on computer viruses in 1984,began to develop strategies for antivirus software in 1988 that were picked up and continued by later antivirus software developers. In 1987, he published a demonstration that there is no algorithm that can perfectly detect all possible viruses.
