Norton Security Doesn't run Scan once in a while

I try to click on either a "Quick Scan" or a "Full Scan", and nothing happens!?!?!  Could it be a "bug" infection that is stopping this? 

At first, switching to Admin run of Norton Security ran it.  Now, not even that.  I do have Family Safety on.   I see resource1.static.digitalinsight.com (42 visits!) listed even though I don't remember ever visiting that sight.  I also see nexus.insight.com shown for right at this moment (part of the Norton Community website access?).  I will try to block this website since this seems suspicious to me.

What about 1063127.fls..doubleclick.net?  Why is this listed as being accessed (I don't remember this site either)?  Quite a few of these:

stags.bluekai.com, i.ytimg.com, s.ytimg.com, choices.truste.com...?

Only the Corel Office Suite and Firefox listed as the Apps used!  Does not explain the above activity.
