Tried all possible settings for ALL shields, even turned ALL shields OFF and it made NO difference!
The only way I was able to get PaintShop Pro to open again was, by uninstalling the 17.2.2288 version and reverting back to an old version…which, as I just now noticed, “screwed” me too, because I forgot to turn off automatic updates for the Program, so it automatically (without notifying me) updated once again to version 17.2.2288…meaning once I shut the computer down tonight and restart it tomorrow, I will most likely find PaintShop Pro to be blocked AGAIN…unless Avast has suddenly fixed the problem which would amount to nothing short of a miracle!
I’ll let you know how it turns out, but don’t hold your breath! :-\
