After navigating to a web page, a popup hijacked the Edge browser.
The popup is a false virus warning, with audio, that repeats endlessly.
I used Task Manager to close Edge browser, but after re-opening, it returns to the hijacked page. There is no time to open another tab, or reach settings. How can this be cleared.
First I tried searching for /user/appdata for Edge entries, and only found a couple, deleted them, but no effect.
I launched msconfig, and set to boot to Safe Mode, minimal. I tried launching Edge in Safe, but you get a warning saying Edge will not launch using the built in administrator account. IE still ran, but no network (as you might expect). I cleared history in IE. But then was unable to relaunch msconfig! Pressing Start flashed a start menu but it disappeared. Selecting the search box wound not search. I ended up launching Control Panel using win+x, and finding System Configuration that way.
When I returned to normal Windows, Edge was set back to its home page.
Clearly this is not a good work around. I can't imagine explaining it to my little niece or grandmother.
Please suggest something more rational.
