I installed Norton Internet security 2006 onto a reformatted PC today and everything seemed okay until I came to turn the computer off. A box came up with "C: DebugLogLog" written in it. After I had clicked okay, the computer wouldn't turn off. I had to literally go to start and close at the computer eight times before it started to close down and then they would just get stuck on the blue screen with logging off. The only way I could turn the computer off was to press the button on the front of the CPU. I uninstalled Norton Internet security and everything seems find so it looks like is the programme that is causing a problem. It doesn't do it on any other computer I have the programme on though.
