In 1983, Fred Cohen coined the term "computer virus",
postulating a virus was "a program that can 'infect' other
programs by modifying them to include a possibly evolved
copy of itself." Mr. Cohen expanded his definition a year
later in his 1984 paper, "A Computer Virus", noting that "a
virus can spread throughout a computer system or network
using the authorizations of every user using it to infect
their programs. Every program that gets infected may also
act as a virus and thus the infection grows."

"Computer Viruses-Theory and Experiments" by Fred Cohen, 1984.
