Bomber (computer virus)

From Wikipedia, the free encyclopedia

Bomber (also known as CommanderBomber) is a DOS polymorphic computer virus known for its technique of "patchy infection". Contrary to the usual method of infecting executables (which is to append virus body to the executable and to change the entry point), it inserts several fragments ("patches") of its code in random places inside the file. These fragments transfer control to each other using various mechanisms.
