I also work on computers for a living and I have dealt with my share of computers affected by this worm. All of the computers that were affected by it that I have worked on have not restarted, only shutdown. Of course I may not have seen all of the versions, so what giovanni42104 said could, and probably is true. As I stated before, all the systems that I have worked on, except for 1 or 2, did not actually show the virus (that is, when a complete scan of the hard drive, from a different system, was done with a completely up to date AV).
Reguardless, your are MOST likely infected/affected by the virus and you need to take the steps mentioned to get rid of the virus and resolve your problems.
Post back with your results.
