9. Computer Network Research Group ITB Concept of Computer Virus l Dr. Fred Cohen 3 November 1983 l Design a computer program that could modify other programs to include a possibly evolved copy of itself. l This evolved copy would then modify other programs and thus continue the propagation and evolution. l The program could easily be spread by unknowing users throughout a computer system or network.
