Just something extra which might or might not be anything since I still haven't reformatted. 
When I try to access my control panel apps the window that comes up telling me that the application is being used by another program simply says 'control panel' in the title bar (the blue bar on top, sorry, don't know the correct name). However, when I try to access my "Set Program and Access Defaults" the same message comes up but this time in the title bar it says rundll32.exe. Also, if I don't touch it, it disappears after a few seconds. I've read that that can sometimes be a virus but Norton 2006 finds nothing.
Any suggestions? Thank you in advance.
