Norton Does Not Recognize Full Scan

My Norton has a big Red X and says "You Are At Risk - Your PC needs to be scanned for viruses and spyware".

So I ran the Full Scan with an internet connection and it found nothing twice. BUT... it will not update the security status and still says I am at risk and my PC needs to be scanned.

I am using a windows account that is not the Administrator, but that shouldn't make a difference.

Why won't it register that the scan has come back negative?
