Here is a bit of info on this thing........
BTW: got several more this morning
A new variant of W32/Sobig, W32/Sobig.f@MM is a High Risk mass-mailing worm. It arrives as an email attachment with a .pif or .scr extension. When run, it infects the host computer, then emails itself (using its own SMTP engine) to harvested email addresses from the victim's machine. In addition, when it propagates, the worm "spoofs" the "from: field", using one of the harvested email addresses.
Note: The worm copies itself onto the infected machine as:
C:\WINNT\WINPPR32.EXE
Caution: An infected email can come from addresses you
