The first computer viruses from the 1970s

  • The Creeper Program is often regarded as the first virus. It was created in 1971 by Bob Thomas of BBN as a security test to see if a self-replicating program was possible.
  • The Rabbit (or Wabbit) virus was developed in 1974. It made multiple copies of itself, severely reducing system performance and eventually crashing the machine.
  • The First Trojan, called ANIMAL, was a game developed by computer programmer John Walker in 1975. To improve the game, Walker created PERVADE, which installed itself along with ANIMAL, examined all computer directories and copied ANIMAL in directories.
