Also keep in mind everyone.. I myself got a "Trojan" way back.. which literally stole my email address and was SPAMMING from it. (which is why I changed internet providers and email addresses) I had signed on one day to see literally dozens of "mailer damon and can not be delivered" emails in my inbox when I had not sent any emails out!!
You can try this site...
http://onguardonline.gov/spam.html At the bottom of thier page is a link to each government site that can help out in any situation regarding the internet. And you will receive a reply within 24 hours. (I did anyway)
good luck.
