I too have had troubles with my email account spamming everyone in my contact list. Many important people in my contacts have let me know in no uncertain terms that they were not happy... I even had a vice president of a local club chastise me on the clubs list serve as knowingly sending out these emails as though I was sharing my internet "frivolities" with the list.
I have run many different scans on my computer, and only one trojan was found and removed, yet the problem still persisted. I ended up deleting my contact list completely to protect them, although the damage had already been done, and changing my account password to see if that will work... so far I have not spammed anyone... but without a contact list, there is no ammo. I will add one or two contacts back and see if I have been successful...
