NIS 2009 Keeps asking to reboot to remove threats

This started happening today on my 2nd day with NIS 2009. Even when I reboot and run no extra apps

 

Any ideas? I had run a full systen scan yesterday, ran CCleaner today and Disk Cleanup to see if that helped.

 

Perhaps I should run a scan from the CD and then another full scan from Windows XP?

 

Thanks to all

Tony
