      A computer worm differs from a computer virus in that a computer worm can run itself. A virus needs a host program to run, and the virus code runs as part of the host program. A computer worm can spread without a host program, although some modern computer worms also use files to hide inside. You can get worms by downloading unknown attachments on email, instant messengers… To prevent worms, you have to keep your computer up to date with window update. You have to use an anti virus program and keep it up to date to prevent worms and eliminate worms. Also, be careful when download something because there might be worm, viruses…
