In the early 70’s a virus was leaked out on the ARPANET, infecting the Tenex operating system. The virus was named “Creeper”, and if your computer was infected, it would message “I AM THE CREEPER: CATCH ME IF YOU CAN”. The virus would gain access independently through the modem and copy itself on to the remote system.
To counteract the attack, another virus called “The Reaper” was created. This was just the start. Today there are millions of worms, Trojan Horses and viruses that your PC has to defend itself against, on a daily basis. It was in 1983, that Fredrick Cohen coined and created the word “virus” to define, what he called, “self replica computer programs.”
