I've been getting a few virii from various people and have looked into this one. It's called Aliz and causes your PC to send out mail to members of your Windows Address Book. It has no other actions, but you'll know if you've received it by getting HTML mails with no body, just a simple subject line. It works if you use Outlook Express (surprise surprise).
