Bob Thomas, a programmer from BBN Technologies wrote the first accepted computer virus 'Creeper' which was an experimental self-replicating program in 1971. His program was designed not to damage but to demonstrate a mobile application. Creeper gained access via the ARPANET and copied itself to the remote system where the message, "I'm the creeper, catch me if you can!" was displayed. The Reaper program was later created to delete Creeper.


Creeper infected DEC PDP-10 computers running the TENEX operating system.
