W11 Home 24H2 Insider Preview.
Updated my Desktop Dell Vostro from W10 PRO TO W11 PRO. Version 22H2 {OS build 22621.963} Today.
This came with McAfee installed, prior to Updating used Revo to uninstall, yet was still able to do manual Defender scans.
Now I find cannot open Windows Security although it appears to be working ok, but not manual scans.
"Services" now show McAfee running. "Everything" show 63 McAfee entries, is it perhaps Dell has reinstalled these?
Would it be safe to stop McAfee in "Services", they do give a warning when I tried.services.jpgeverything.jpg

When attempting to remove an Antivirus product, use that companies removal tool.
Almost all AV products require a similar method.
You may have to re-install the product, then run the removal tool...

McAfee removal tool



For future reference, just Google: <AV Name> removal tool
Even with the removal tool, most companies don't make it easy... so read ALL the instructions carefully. :-)

    Other Info
    Still assembled, still runs. Haven't turned it on for 15 years?
Finally managed to get Windows Security to work including quick scans.
As for McAfee Removal Tool tried numerous times (F***ing useless) although each time it stated uninstalled successfully.
To tell the truth I tried so many different methods over many hours to finally rid my computer of its interference including Powershell commands,
that I could not give a definitive answer as to how it was solved, though lastly deleting certain McAfee settings in "Everything" might have done the trick.

Different issue with Defender to yours but same cause. I had to do a lot of registry searches as well as deleting list in Everything.
I also agree the removal tool is a non starter. :(

DefenderUI

The user interface of Windows Defender is very awkward to use, and it hasn't improved at all in Windows 11. DefenderUI significantly improves usability and unlocks many hidden security features. I don't use Windows Defender, but I reckon that some of you might find this very handy...
