Windows has encountered a critical problem and will restart automatic

I have moved this thread over, as I felt it was a different issue.

Previous thread - Most of the main services will not start?

I'm running win 7 Ultimate 32 Bit, which has been fine up to a few days ago when on start up reaching the desktop I started getting a window saying "Windows has encountered a critical problem and will restart automatically in one minute." it would then restart and continually loop this way.

I booted to safe mode and had no restart message, so was able to run a virus scan using Microsoft security essentials, however if I booted to safe mode with networking the restart window would show again.

I have looked for the Gbp Service, which I was advised might be causing the problem, but cannot find this in services running.

However, I have found that by discounting the internet, the restart issue does not show, but as soon as I connect to the internet, it pops up and the system restarts.

Does this indicate a virus or trojen of some kind?

Any suggestion how I stop this, as I cannot run a up to date antivirus program without being connected to the internet to get the latest updates?

Happy.

Hi Guys

The problem is now fixed, after trying all the things suggested (thank You!), I created a Windows Repair CD and booted to this, this then allowed me to do a System Restore, but this advised it had failed, however after restarting the restore had actually worked? Thus removing the restart alert and allowing me to connect to the internet.

I ran further virus and spyware scans, no virus's found, but there were a few spyware, which were successfully cleaned.

System now in perfect working order again!

Thank you again everyone!

Happy.
