I'm using Windows 11 on my new laptop and a popup suggests that it's associated with a microsoft product. When I open it from the tray icon I encounter this antivirus software (see screenshot). I'm unsure if I accepted it or not.
1. I already have a different antivirus (McAfee) so I don't know...
Couple of suggestions:
-Update all device drivers on your laptop
-Check & optimize the power plan settings on your pc.
-Make sure your windows is updated .
-Review & close unnecessary background processes (this helps me in the past).
-Run an antivirus scan
Hope it helps, if not maybe you should...
I had a similar story with one of my kids' computers last week.
This is so frustrating so I"m sorry that it happen to you!!
I give it to a local tech store which help to recover some data (But it cost a lot!).
