Hi, I do not recall setting up custom scans, it just says that. Another thing I find difficult to fathom.
Don't know about the computer fellow. I just know that he supports Avast. Before this computer I had a HP, - virtually no issues with that one at all. It just got too old, but had served us well.
The Windows Defender is not as you described, but will "stop" it when scanning. Avast cannot scan password protected things, and there is a host of those.
All in all, I'm not happy w/Avast, and will not pay again for it. I will run the Malwarebytes and see what happens.
Thank you very much.
