Are you having the problem with LW popping up all the time too? My best advice would be to go to Norbiesworld (click on link below). He sees this problem a lot & will be able to help you, it's all free. If you go to his site & register, follow the directions for free computer help. Download Hijackthis & post the log in the Viruses, Trojans, Spyware section of his forum.
