W32/Badtrans-B Internet Worm

Got hit with this worm this afternoon and was bombarded with undeliverable mail from people I never mailed to today because of this worm. They appear to only have been sent to dirtrider.net members. Don't know how because I've never e-mailed any of them nor do I have them in my contact list. Nobody else seemed to get hit only members here so make sure your antivirus program is up to date. I hadn't even opened the suspicious mail but it made no difference. I guess it's called W32/Badtrans-B.
