Hi, I was watching a video in Mecachafe and then my computer got something that would open firefox every 30 seconds with a popup. So when I did the scan It found the problem but said I needed to restart the computer to take effect. So when I restarted and got to the part that said "Windows Xp Home Edition" the blue bar stoped and the computer restarted. I told my Math teacher about the problem and he said It was drivers conflicting with each other. So I dont know how to fix the problem. PLEASE HELP!!!
