Hi I lost control panel about a couple days ago and now its telling me that when I try to add/remove programs "I need to contact system administrator due to restrictions set on this computer. I downloaded a trojan I believe that is called win32/hostblock. I did do a scan with Hijackthis but I see thats not up to date. Please help before this problem gets any worse!! Thanks in advance to whatever help I can get. I have windows XP sp2. Dimension E310.
