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.

1260, or V2PX, [1] [2] was a polymorphic computer virus written in 1989 by Mark Washburn. Derived from Ralf Burger's publication of the disassembled Vienna Virus source code, the 1260 added a cipher and varied its signature by randomizing its decryption algorithm. Both the 1260 and Vienna infect .COM files in the current or PATH directories ...
A polymorphic engine (sometimes called mutation engine or mutating engine) is a software component that uses polymorphic code to alter the payload while preserving the same functionality. Polymorphic engines are used almost exclusively in malware , with the purpose of being harder for antivirus software to detect.
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]
ARCV-n is a large family of viruses authored by the Association of Really Cruel Viruses (ARCV) group through October - November 1992. and polymorphed [clarification needed] with the PS-MPC virus generation tool (hence they are very similar). A polymorphic virus mutates itself to avoid detection by traditional antivirus and antimalware software. [1]
Bulgarian virus writer Dark Avenger wrote 1260, the first known use of polymorphic code, used to circumvent the type of pattern recognition used by antivirus software, and nowadays also intrusion detection systems. [citation needed] [35] [36]
