I'm signed up to so many programs, I don't know which one is spamming me and playing around with my email address. First comes the porn. You know, "#1 Male Organ Enlargement on the Net"

, "Hardcore XXX", "Free Porn Through Email", etc. Now I'm starting to get virus emails as well

. I have a lot of people using my computer, if they accientally open it, it'll be a disaster.
So far, 3 porn ads and 2 virus emails yesterday. It's not going to do good blocking them, even with a filter program, since it's always fake email addresses.
Does anyone have some idea which program might be the culprit? I haven't a clue HOW I'm even going to check them out one-by-one...
