Hi, Fink. Thanks for the reply. I downloaded and tried a few earlier versions of FastStone with same results. I get the not responding and freezes up the program. Is there another good image viewer that may be worth trying?

Also, I just scanned a few other files using Microsoft Defender and they give the same result in finding that PUABUndler threat. I never received this before when scanning files. It must have started after I just recently updated ccleaner. Is there a way to remove that add-on and prevent this threat from occuring?
