Sobig Worm Hitting Us on the Rebound

The Sobig worm making the rounds again is officially W32/SOBIG.F. It appears to be using spam as it's source of transport so it affects, if not infects, Macs. We are getting dozens of bounced messages per hour by anti-spam/anti-virus software to the email address that we have prominently displayed in the past, the source of most of our spam. Spammed by anti-virus software, now that's a new one.
