I've been getting several emails the past couple of days containing the "SoBig" virus. For those of you who don't know, the message usually just says "re:details" or "Thank You" or something like that, and has an attachment somewhere around the 100kb mark.

Anyway, make sure your virus programs are up to date, and even run a couple of the free online scanners. Here are a couple of good ones:
