Hello, my friend gave me his used computer with W7 32bit and it came with this problem, I don't know what he was messing with. After and only after plugging in the ethernet for internet, in Normal mode, about 1-5 minutes later I get an error window with the message "Windows has encountered a critical error and will now restart in one minute" and the heading "You are about to be logged off". At that point no matter what I do the computer will restart in about a minute. I am posting this in safe mode where it works fine. Another weird thing, I think it's related, but without internet Avira antivirus and Windows Firewall will be on and work fine. After plugging in internet, they both turn off. Once I had Avira open while connecting to the internet, and Avira's firewall status indicator turned off right in front of me. When I tried to turn it back on I got a new window with the message "The service cannot accept control messages at this time." and with a heading that was a filepath leading to ccuac.exe. I did the rounds with Broni in the virus and malware forum, he said I do not have any malware. http://www.techspot.com/community/t...ection-you-are-about-to-be-logged-off.200822/ So I hope my extensive details will help someone help me here. Thank you for reading.
