Error during check!: Xuron55 (Datei C:\WINDOWS\win.ini kann

My computer sporadically reboots itself. I have update the virus definition files and have the latest MS patches. When running spybot I get the following error and I am not sure if they are related:

_____________________________________________________________
Error during check!: Xuron55 (Datei C:\WINDOWS\win.ini kann nicht geöffnet werden. The process cannot access the file because it is being used by another process) ()

Any suggestions.
