Concept of computer virus l.jpg
Concept of Computer Virus

  • Dr. Fred Cohen 3 November 1983

  • Design a computer program that could modify other programs to include a possibly evolved copy of itself.

  • This evolved copy would then modify other programs and thus continue the propagation and evolution.

  • The program could easily be spread by unknowing users throughout a computer system or network.
