Hell yes that's what they are doing. I had the same thing going on. I got an email from
[email protected] yesterday, my husband has that email so here I go flying like a wild fool in there and he has no virus......... I come back in here and look at the header and the damn thing came from someone in flippin Brazil somewhere, but it LOOKED like the virus came from his email addy.
I also ran all the scanners and the program that someone here told me to run, and no sign of a virus anywhere............. so chances are you are ok. For the record, that is an exact email I have gotten more than a few times.
