NIS "open" doesn't work - and small panel that showed 'protected' etc. gone?

When I double-click the NIS icon nothing happens.  I've also tried right-clicking and 'open' - again, nothing.

How do I access things like quick scan, full scan, history, etc.?

 

I also used to have a small icon/panel in the corner of my computer that had the Norton logo and a green "protected."  This is now gone. 

 

How do I even know that NIS is installed and functioning properly?

 

I'm running Windows 7 Home Premium.  I've checked and Windows Defender is off.  I've also just removed and re-installed NIS (and did a full restart).

 

Any assistance would be very much appriciated...I feel sort of "naked" without all the gizmos :-)
