Thank you for responding.
I used Advanced Exceptions:
1. made a folder for all my c folders
2. chose the new folder for the Exceptions address
Works so far.
The documentation that you sent me to has the
dark theme. Mostly unreadable. Your or someone's
comments made it possible to know what to do,
but I couldn't use the images.
The dark theme makes me feel uncomfortable using
Avast, and now that Consumers Reports has written
an article about using Dark Themes, I'm inclined to
go elsewhere or just use Microsoft's Security.
It is impossible to see what is going on and I make
many errors.
Anyway, thanks again for responding.
