nvidia physics detected as a high threat???

I upgraded nortons to norton internet security  22.5.0.124 I am on windows 8.1 pro.  This morning I booted up the computer and left the keyboard for a while when I got back I had a window up that said

I doubt that nvidia in infected, I think that it is the new version of norton internet security that isn't understanding the physics drivers.

 

Doesn't anyone have any ideas of what might be happening?  by the way I had a choice ignore or quarentine .. so I chose to close that window (which I think put it into quarantine).  Hopefully I can pull the file back later
