In 1983, the term 'computer virus' was coined by Fred Cohen in one of the first ever published academic papers on computer viruses.

The first known that appeared 'in the wild' was ' Elk Cloner', in 1981, which infected Apple II computers. The Creeper virus was followed by several other viruses. Some people consider 'The Reaper' the first antivirus software ever written – it may be the case, but it is important to note that the Reaper was actually a virus itself specifically designed to remove the Creeper virus. The Creeper virus was eventually deleted by a program created by Ray Tomlinson and known as ' The Reaper'. This computer virus infected Digital Equipment Corporation's ( DEC) PDP-10 mainframe computers running the TENEX operating system.
