How do I remove a persistent fake-virus alert popup?
I've got a Surface Go 4 running Windows 11 in my family where today the user clicked "allow" on a popup message she got asking about cookies or something while browsing in Edge. Since then, the PC gets a popup in the lower right corner. She got maybe 15 different versions of the popup. It stays on-screen for 10 to 30 seconds, then goes away without clicking on anything. The next will pop up in 5 seconds to 5 or more minutes. Headings include "(McAfee logo) Virus Alert", "(Windows logo) Sytem Damaged!", "(microsoft logo) "Microsoft Windows Defender TROJAN found in /Win32!", "(shield image) Virus & threats protection - Threats found (16)."
All have some spelling or syntax errors but otherwise look convincing.
All have the same link snippet: "crot50ohubcc738pnb00.loopdeviceconne..."
We haven't clicked anywhere on or near the popup when it's on screen.
Steps I've tried:
Windows defender checked status: has been running ok, last updated last night (9/2224) around 10:20pm.
Powered off, shut off network, powered on, Windows defender quick scan: came up clean. No pop-ups while network was off.
Windows defender offline scan: behaved normally (warned of reboot, reboot, scan) came up clean. Pop-ups resumed when network was turned on.
Taskmgr doesn't show anything I recognize as bad in startup apps list or in running processes, but I'm not current enough to know what processes might be bad.

Hi, these are push notifications.
To remove specific Edge push notifications:
Enter edge://settings/content/notifications into the URL bar.
For any entries you don't recognize in the Allow section, click the ellipsis (3 dots) to the right of each entry and either Block or Remove it.
You should see an entry for "crot50ohubcc738pnb00.loopdeviceconne...".
You can also toggle Ask before sending to off if you wish to block all notifications.
I figured it out. I stopped the pop up first by going to Settings-Notifications and saw this url under notifications from apps and other senders. I was able to stop that notification - then follow through with blocking from the Edge Notifications as mentioned.
Drag the browser window to where they're not blocked or press Alt + F > Settings
Thanks for this - the pop up I mistakenly allowed (for the first time ever!) extends over the three dots - I can't get to them to block it. I copied the site listed there under allow into the site blocker, but I think that will just block that site permanently and not fix the current pop-up. Any ideas for what to do if on my screen I can't get to the 3 dots to block?
there are several different types from a fake mcafee popup, your computer if infected, you have a virus, etc, all popping up on the lower right of the screen.
I googled how to stop by deleting cookies and stopping popups on settings but that also didn't help. This has been nonstop for 4 days. I just downloaded malwarebytes and ran a scan after my norton antivirus picked up nothing. It showed 54 potential threats so I quarantined them and there have been no pop ups for the last 10 minutes. Crossing my fingers here. Thank you for your quick response. I will monitor and advise.
