In a livejournal post, a University of Michigan student describes her frustrating experience with a Mytob infection. There are literally hundreds of variants of Mytob, but in general Mytob variants are mass-mailing email worms that compromise system security by terminating processes related to various antivirus software. The Mytob family also typically disables the XP SP2 firewall, and modifies the HOSTS file to prevent access to antivirus updates and certain other websites. Depending on the Mytob variant, in addition to the email vector the worm may also automatically infect susceptible (unpatched) systems via the Internet by exploiting the LSASS vulnerability (MS04-011) or a buffer overrun vulnerability in the RPC interface (MS03-026).

Plagued by spyware and adware that keeps reinstalling itself everytime you remove it? If you haven't kept your security patches up to date, the resuscitating spyware and adware may be the result of an Internet worm that reinfects your computer each time you access the Internet. Once the worm is in place - which will happen silently and without any action on your part - the worm installs a remote-access Trojan that then downloads adware and spyware and installs it to your system. All without your knowledge or consent. And it's not a single worm you need to worry about - there are multitudes of them circulating every corner of cyberspace.
