zoom.com is capturing your screen

I am on a Mac and there is purple icon in my menu that I have never seen before, when I scroll over it, it says "zoom.us is capturing your computer screen" but I was not on a live zoom call.  first, I quit zoom.   still there.  then I just went ahead and deleted the app from my computer: still there.  now I am going to restart.  better not be there when I get back.
