Au contraire, it is myself, that is the limited user!
I noticed your last fixlist.txt included Chromium references.
Nobody has intentionally downloaded that app, however I had noticed that the shortcut app logo was on the desktop.
And now it is gone after your reset point.
Thank you for your help...this week.
It feels better already.
On a side note, before your reply, recall that the popups were occurring automatically on MS Edge (instead of Chrome).
I tried to uninstall MS Edge (from memory).
I don't know if I was able to uninstall MS Edge, but actually, on purpose, deleted an important file:
C: users: ryan: AppData : Local: MicrosoftEdge: folderxxx
after deleting this file(folder), all the popups were appearing as an error window.
Probably since MS Edge would not allow a window to open it within.
Added to the fact that MS Edge was disabled.
Regardless at the end of the day, I reinstalled that file(folder) from the trash.
Alas all is good.
