Creeper and Reaper

Creeper was the first computer worm, while Reaper was the first antivirus software, designed to eliminate Creeper.

Creeper was an experimental computer program written by Bob Thomas at BBN in 1971.^[1] Its original iteration was designed to move between DECPDP-10mainframe computers running the TENEX operating system using the ARPANET, with a later version by Ray Tomlinson designed to copy itself between computers rather than simply move.^[2] This self-replicating version of Creeper is generally accepted to be the first computer worm.^[3][4][5] Creeper was a test created to demonstrate the possibility of a self-replicating computer program that could spread to other computers.

The program was not actively malicious software, as it caused no damage to data, the only effect being a message it output to the teletype reading "I'M THE CREEPER : CATCH ME IF YOU CAN"^[6][4][2]

Reaper was the first anti-virus software, designed to delete Creeper by moving across the ARPANET. It was created by Tomlinson in 1972.^[2]
