@SendOfJive and AllenM:

Thanks for the feedback.

To clarify .... I do not have Quick Scans scheduled .... they are only initiated during idle time.

The only user scheduled scan I have is a full scan scheduled once per week .... that scan ran yesterday at 13:21 ... the (unscheduled) idle time Quick Scan ran yesterday at 19:00 ... and the pop-up occurred yesterday at 20:37 ... so it appears that pop-up was from the (unscheduled) idle time Quick Scan.

According to my NIS History .... Since installing 19.5, Idle Quick Scans have been running between one and three times per day (I guess that depends on how frequently my computer is idle) ... and yesterday was the first time I saw a pop-up (since installing 19.5 last week).

I also agree that ALL pop-ups that say "no threat found" should be suppressed .... I thought that's what the fix (that was part of 19.5) was supposed to do.
