To answer a few of your comments;
I have reset my email password. No problems since the last reset.
I can’t attach a screen shot of the Avast virus log since Avast I can’t highlight - and hence copy the log page.
I believe I understand the difference between the PUP and the bad stuff.

I’m surmising from all the kind advice that these “memory” viruses aren’t really viruses that are currently affecting my computer. This seems likely to me since all the other remedial services I downloaded are running clean - as well as the “full” and “quick” Avast scan. The consensus seems to be that my computer is likely uninfected - right? Correct me if I might be wrong. Thanks again.
