I've received about 50 (I am *NOT* kidding!) copies of that in the past 24 hours. I read my mail on a unix box, so I'm able to go into the message without any danger. This is what is screwing you guys:

Basically, it's a straight-up virus masquerading as a URL in the message. If you're using one of Unka Bill's retarded programs that automatically load embedded web pages, you're as screwed as a 98-lb inmate.
