He created a virus, as part of his doctoral thesis, in an effort to find ways to defend computer systems from self-replicating programs. There are others who claim that computer viruses existed well before 1984 when Dr. Cohen did his research. The debate over the appearance of the first virus will probably continue for a long time. Currently it does not appear likely that computer scientists will agree upon an 'official' definition of the term.
