Interesting.  None of our machines so far that have been infected are
trying to contact sco.com on port 80.  I'm curious if there are multiple
varients??

We have identified this virus as the MyDoom/Novarg, and Symantec did
confirm our submission as such.

We are experiencing what appears to be a new varient of the MIMAIL
virus. We've had several machines infected now, and I've created a
quick signature:

Although Mimail.Q did also come out today, what you're describing is
Mydoom/Novarg, which is spreading more rapidly than Mimail from the
looks of it. Details from the AV companies are sketchy at this point,
but, aside from spreading via SMTP and KaZaA, the copy I looked at
appears to start up 63 threads all requesting the index page of
www.sco.com every 300 milliseconds.
