The Creeper virus was first detected on ARPANET, the forerunner of the Internet, within the early Seventies. Creeper was an experimental self-replicating program written by Bob Thomas at BBN Technologies in 1971. Creeper used the ARPANET to infect DEC PDP-10 computer systems operating the TENEX working system. Creeper gained access through the ARPANET and copied itself to the distant system the place the message, “I’m the creeper, catch me when you can!” was displayed. In response, free, open-supply anti-virus instruments have been developed, and an business of antivirus software program has cropped up, promoting or freely distributing virus protection to customers of varied operating systems.

The Nobel Prize-profitable biologist David Baltimore devised the Baltimore classification system. The ICTV classification system is used along side the Baltimore classification system in modern virus classification.
