Bob,
I'm getting the same emails you have.......Expect 1,000 more before this worm has taken it's course...............Most likely not from your system (I've gotten nothing eminating from my own network yet), just the worm taking hold of your email address from another users system, and blasting it out to a gazzilion other email addresses it has found and assimilated.........Kind of like the borg...........
