e/Helpful worm

Information
has gloss	eng: A Helpful worm is variant on a computer worm which delivers its payload by doing "helpful" actions instead of malicious actions. Welchia was a major example of a helpful worm - utilizing the same exploit which caused the Blaster worm. Infected computers automatically began downloading Microsoft security updates for Windows without the users' consent and automatically rebooted the computers. One of these updates was, incidentally, the patch which fixed the exploit.
