create a worm to stop a worm

Intentions of the worm
This worm spreads by exploiting a hole in Microsoft Windows. It instructs a remote target system to download and execute the worm from the infected host. Once running, the worm terminates and deletes the W32/Lovsan.worm.a process and applies the Microsoft patch to prevent other threats from infecting the system through the same hole. When the system clock reaches Jan 1, 2004, the worm will delete itself upon execution.

Kinda cool, but a worm is still a worm.

M$ Should make a bunch of worms to close off all shit in their server...

It would get more attention than an update... which obviously so many epople don't do :P
