Hi,

first of all I hope you have the Microsoft patch:

Microsoft Security Bulletin MS04-004
http://www.microsoft.com/technet/security/bulletin/MS04-004.asp

My Doom, which is also known as ?Novarg? or ?WORM-MIMAIL.R,'' spreads by mailing itself to computer networks, where it creates an open ?back door,? leaving the computer and its data exposed to the entire Internet. Hackers can then use the infected computer to gain access to the corporate network and all information stored within it. The virus also spreads itself using the Kazaa peer-to-peer file-sharing network.


The immediate purpose of the back door in the My Door virus appears simply to use the infected computer to further spread the virus.

Hope this helps.
