System reboots. I think I got a virus in my compaq presario and I have Norton antivirus. Yeah

Question

I think I got a virus in my compaq presario and I have Norton antivirus. Yeah Norton.... I ran the recovery disk which wiped out all of my documents, etc. I can run it in safe mode but it shuts down and reboots in regular mode. I am trying to find the problem. I am going to look for updated drivers next. Any suggestions?
