SoBig Virus
We have seen an increase in the number of reports of the Sobig virus worm.
We have seen a large number of German political propaganda spam e-mails that are originating from Sober worm infected computers. These messages are not infected but are coming from infected computers.
This particular family of virus's has been around for a while but the Sober.O's primary characteristic is a zip file attachment.
For more information about this virus see this PC World article.

See Symantec's Sobig page for a removal tool and more information about the worm.
