Question

When did the term “computer virus” arise?
Steven White, manager of IBM Research's Massively Distributed System Group, offers some complementary information: The term "computer virus" was coined in the early 1980s. Fred Cohen, then a Ph.D. student at the University of Southern California, came up with the idea of using self-replicating software, which spreads by attaching itself to existing programs as a way of attacking the security of multi-user computing systems. He showed this idea to Len Adleman, his thesis advisor. Adleman pointed out the similarity to a biological virus, which uses the resources of the cell it attacks to reproduce itself, and the term "computer virus" began its journey into everyday English. Since then, computer viruses have mimicked their biological namesakes, spreading digital disease around the world. And here at IBM Research, we are taking inspiration from biological defenses to viruses and creating a kind of immune system for cyberspace, which will be able to find, analyze and eliminate new computer viruses from the world's computers quickly and automatically. Alex Haddox is product manager of the Symantec AntiVirus Research Center, which manufactures Norton AntiVirus products. He adds: The history of the computer virus began in the 1940s when John von Neumann published a paper called "Theory and Organization of Complicated Automata," which documented the possibility of replicating computer programs. John Conway is credited with creating the first "virus" in the form of a life emulating program called the "Game of Life" in the1960s. In the 1970s the first true self-replicating programs, referred to as "organisms," were written as experiments in artificial intelligence on UNIX systems and used in small, isolated network type games by large research companies. In 1983 the term "virus" was first coined to describe self- replicating programs by Frederick Cohen and his colleague, Len Adleman. The first reports of serious damage from a PC virus occurred in 1986; the infection was caused by the "Pakistani Brain" virus, which was written by two brothers, Basit and Amjad Farooq Alvi, of Lahore, Pakistan.
