Questions about Trust Level change

Hi Guys,

My computer was offline for a few days. After receiving the latest patch and updates, I ran a full system scan. Afterwards, I noticed that the trust level on the main screen (in the first box, underneath CPU) had dropped from 88% (where it’s been since I upgraded to the latest version of NIS a few months ago) to 79%. I’m not surprised there was a change as I also received some Windows updates and recently uninstalled Chrome, but 9% seemed like a large drop.

Is a 9% change in the trust level something to be concerned about? Do users need to be concerned with the trust level as long as it says the system is secure and/or is there a % range the average computer should be in?

Any feedback would be greatly appreciated!

(Running latest version of NIS on Windows 8. )
