Norton Utility freezes while scanning

Hello, I just downloaded Norton Utilites 15 and am having a problem doing a system scan.

While doing the scan the computer stops at the file

HKEY_CLASSES_ROOT\Krnlprov.KernelTraceProvider\curver

It appears to be scanning, but I have let it sit on this file for over an hour and it will not go any further.

I have tried the scan twice now.

Looking for some advice. I am running Windows 7.

Thanks.
