Sirefef and Zeroaccess causing Windows to restart automatically in one minute

Hello, I am facing a huge problem now. Microsoft Security Essentials shows an alert on Siferef/Zeroaccess infected file SERVICES.EXE and it will display a messages saying:

“Windows has encountered a critical problem and will restart automatically in one minute. Save your work now.”

My computer reboots repeatedly after detecting Zeroaccess and Sirefef and I can do nothing about it. I already run several antivirus programs but none of them helped me out to delete the Trojan. In fact, I was not able to complete the scan because of this constant rebooting of Windows.

I need immediate help to stop the reboot loop. Please tell me what to do. I wish I can save the PC and solve this issue without going through a reformat course.
