Re: mysterious/suspicious internet activity. [solved] [REALLY SOLVED]

After a weekly patching and several boots, what Ed suggested continues 
to work.  This includes e-mail, browser, dnf upgrade, dnf install, zoom, 
and video downloads (via Firefox add-on and via command line).  As best 
as I can see, nothing got broke and everything works as it should.  So 
I'm tagging this REALLY solved.  I thanks Samuel for bringing up the 
additional caution, Ed for the solution, and others for the further 
discussion.

I did find a youtube video of a musical performance of Man of La 
Mancha.  I tried to watch it.  Poor focus.  I did not watch all the way 
through.  But now I know where the song "To Dream the Impossible Dream" 
comes from.
