The sudden appearance of the Avast “Clean-up” window looks like malware.
I note that the one I saw (for the first time ever) today at least had a “Cancel”
button. (small comfort).

What the f— does the “Resolve” button actually do:
–Take you to the website to download the actual app???
–Actually delete files from my machine???

Definitely bad manners all around and definitely, from a marketing stand-point, a real turn-off.
