This mess all seems connected somehow:
While my W10P HP Envy was browsing w/ Firefox, I turned on Settings> Win Defender> LimPerScan,
and immediately received(attached JPG:) 3 Avast warnings (which stupidly prevents text capture for research
) & browsing failed (refreshed browsers seem fine).
Ms is getting more stupid about signing its stuff, but I still aborted them.
Then, trying to 'remove the file', searching C:\ for "am_delta_", Windows Explorer found ONLY "background.js" which Notepad.exe indicates is from Blur by Abine Inc. (which I have used for several years.) but text search canNOT find that text in that file.
Is there still/now a problem with Avast Premium and WDefender 'occasional scan',
or has someone tried to sneak in on Ms sloppiness again, or ...?
PS: This post's "Attach" tool GUI is poor(no att confirmation), & [Preview] of this post prevents attachment viewing, which makes Avast's 'error text capture prevention' all the more obnoxious.
