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 ...
Brain is considered the first IBM PC compatible virus, and the program responsible for the first IBM PC compatible virus epidemic. The virus is also known as Lahore, Pakistani, Pakistani Brain, and Pakistani flu as it was created in Lahore , Pakistan, by 19-year-old Pakistani programmer Basit Farooq Alvi and his brother, Amjad Farooq Alvi.
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.

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 ...
This is known as polymorphic malware. Other common techniques used to evade detection include, from common to uncommon: [ 61 ] (1) evasion of analysis and detection by fingerprinting the environment when executed; [ 62 ] (2) confusing automated tools' detection methods.
Antivirus software (abbreviated to AV software), also known as anti-malware, is a computer program used to prevent, detect, and remove malware. Antivirus software was originally developed to detect and remove computer viruses , hence the name.
