Windows Defender doesn't appear to be completely disabled by Norton Security Installation

I have a Dell Inspiron 17 laptop running Windows 8.1 (64) with Norton Security installed. I downloaded and installed the Belarc Advisor Program (mainly to record  current hardware and software configuration and ser #s) and it is reporting out of date virus definitions in Windows Defender. On my other Windows 8.1 (64) PCs with Norton Security or NIS installed the Belrac Program is not seeing Windows Defender or reporting its status.

Has anyone seen this? Is there a solution? Should I just ignore it?
