Not only is today the celebration of our Irish forefathers but the 40th anniversary of the computer virus. The first computer virus was called The Creeper. The Creeper virus was first detected on Arpanet, the forerunner of the internet, in the early 1970s. Creeper was an experimental self-replicating program written by Bob Thomas in 1971. Creeper used the ARPANET to infect DEC PDP-10 computers running the TENEX os. 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 created to delete Creeper.
Back in the days when Apple was the major computer retailer another virus called the Elk Cloner was spread via floppy disk. The virus in the pic here shows an original BSOD. The virus was called Brain(c) and apparently gave an address to where the computer could be fixed. Funny how our business is called Brain Child Computer Repair.
