Low system security rating by Belarc Advisor - Need help

I use Win'7 system protected by Norton 360 and did a check of the system with Belarc Advisor , which reports the security rating as 0.63 out of 10 and very concerned.

 

Norton 360 protection is fine but the low benchmark ratings by Belarc is worrisome and Need help to plug out any security vulnerabilities and attach the Belarc advisor report for suggestions, please..
