The first known polymorphic virus was written by Mark Washburn. The virus, called 1260, was written in 1990. A better-known polymorphic virus was created in 1992 by the hacker Dark Avenger as a means of avoiding pattern recognition from antivirus software. A common and very virulent polymorphic virus is the file infecter Virut.

OneHalf is a DOS-based polymorphic computer virus (hybrid boot and file infector) discovered in October 1994. [1] It is also known as Slovak Bomber, Freelove or Explosion-II. [ 2 ] It infects the master boot record (MBR) of the hard disk , and any files with extensions .COM , .SCR and .EXE . [ 3 ]
The Smeg Virus Construction Kit (or SMEG) is a polymorphic engine written by virus writer Chris Pile, known as The Black Baron. SMEG is an acronym for Simulated Metamorphic Encryption Generator. SMEG is an acronym for Simulated Metamorphic Encryption Generator.
The virus was released in its most recent version in early March 2002. It was written by the virus writer "Mental Driller". Some of his previous viruses, such as Win95/Drill (which used the TUAREG polymorphic engine), have proved very challenging to detect. When the virus is first executed, it checks the current date.
Metamorphic code is used by computer viruses to avoid the pattern recognition of anti-virus software.Metamorphic viruses often translate their own binary code into a temporary representation, editing the temporary representation of themselves and then translate the edited form back to machine code again.

Sality is a family of polymorphic file infectors, which target Windows executable files with the extensions .EXE or .SCR. [1] Sality utilizes polymorphic and entry-point obscuring (EPO) techniques to infect files using the following methods: not changing the entry point address of the host, and replacing the original host code at the entry point of the executable with a variable stub to ...
