I am having a serious problem with my computer. I have been listed on a few sites like spamcop for sending out spam. I beleive I have some kind of trojan or spyware on my computer that is sending out spam. I have tried using Spybot, Adaware, Bazooka, Avg, Panda and Swat it to scan my computer to find anyhting that could be causing this problem with no luck. My computer continues to be listed after a couple of removals from the list when I thought I had the problem resolved but continue to be added to the list. Are there any other programs out there that I should try or anyone have any idea how to resolve this problem without formatting my cpu.
