Sends email to addresses harvested from the infected system.

I had always gloated to people about never once getting spam in my gmail inbox, and very little overall. Now this.
You can be as careful as you want but you can't force everyone you've ever e-mailed to be careful and not get viruses or the people they've forwarded your e-mails to.

You're not the one with the infected computer (you've scanned recently?) so I wouldn't stress out, if you have e-mail your going to get some once in a while.
