Thanks DJM!

McAfee is calling this thing W32/Mydoom@MM - see link http://us.mcafee.com/virusInfo/defau...virus_k=100983

Aliases listed are:
Novarg (F-Secure), W32.Novarg.A@mm (Symantec), Win32/Shimg (CA), WORM_MIMAIL.R (Trend)

This thing is nasty and propagating like MAD! My company is seeing about 100 per hour for just THIS virus. So far seeing PIF, EXE, CMD, ZIP, and SCR file extensions.

AV vendors that have updates (that I know of) are: McAfee, Sophos, Norman, Symantec.
