After a virus worm enters computer system, the operating system (OS) creates single thread for the worm’s execution. Next, the worm spawns or creates another process that is an exact duplicate of the original process. In other words, the worm makes an exact duplicate of itself within the computer’s memory. The worm continues to duplicate itself each time the OS manages the worm’s process till it paralyzes the OS completely and forces it to shut down.
