Need help with nasty infection...

Hello, I its been a while, but I did just want to provide you with a last update. Unfortunately, I had to surrender and get a new laptop, but I do appreciate all the help I received. I had tried to upload those files from my infected pc, but discovered I could no longer connect to the internet or even run the troubleshooter because it had apparently been removed from my registry. However, I am still very interested in analyzing this pc and was wondering if avast! offered any service that would encompass a further analysis. Thanks again!

P.S.
Non related question: When it comes to setting special permissions for different programs, besides SYSTEM and administrators, should there be any other groups present or does it vary from PC to PC?

The problem looking at the latest comments may actually be a hardware related problem in conjunction with a minor infection

The groups will vary dependant on how many users are present
