This is a perfect example of why you need to always keep your critical window updates updated. Next time your computer starts up and the shutdown command is initiated open cmd.exe - type "shutdown /a" to abort the shutdown.

If your computer does not give you enough time to do this start it up in safe mode. Check your msconfig and registry for malicious keys. Run your Norton(UPDATED). That should do it for ya~
