When you say you "checked for virus", what did you check with? Were you as thorough as described below? http://www.elephantboycomputers.com/page2.html#Removing_MalwareMS-MVP - Elephant Boy Computers - Don't Panic!

i used symantec anti-virus and webroot antivirus and spysweeper

Please go through the malware removal steps at the link, then. I don't particularly care for any of the programs you used and it's also important to do the preparatory work.MS-MVP - Elephant Boy Computers - Don't Panic!
