i had three trojans on mine
I just ran norton antivirus on them.Norton discovered them in the first place (though I knew there was a problem somewhere) It said however that it could not remove them. After several hours of reading I discovered that you have to remove them with computer in safe mode. Maybe that will help? I have windows xp. On xp you get to safe mode thus: start>run> type in "msconfig" without quotes> and then sellect bootinit. tab. safeboot is first option reading down. Good luck
