In 1984, Fred Cohen of the University of Southern California published the first paper describing a coded program that could replicate and infect other machines, which he called a “computer virus.”
One of the few solid theoretical results in the study of computer viruses is Cohen’s 1987 demonstration that there is no algorithm that can perfectly detect all possible viruses. He also believed there are positive viruses and he had created one called the compression virus which spreading would infect all executable files on a computer, not to destroy, but to make them smaller.
In his career, Cohen wrote over 60 professional publications and 11 books, and he regularly provides consulting services for top management worldwide.
