Windows 10: Malware not found in scan/memory integrity shut off

Hi, I'm having two problems and I'm not sure if they are related but any and all help is so appreciated. First, there is malware on my computer. It's not showing up in any scans, and I've tried them all, but it keeps coming back. It started with browser hijacking, then shutting down the browser completely and something that looks like my command prompt pops up but it didn't look quite right and I couldn't use it and then it suddenly disappears as the browser window comes back. I noticed it as an extension on my browser as well, downloading gaudio helped to remove the extension but it still co

unable to turn on memory integrity

unable to turn on memory integrity and it suggests a incompatible driver but no driver is listed as incompatible

 

Memory Integrity No Longer Functioning

I received a popup notification from Windows Security that Memory Integrity was off. ssdudfu.sys, VIA_USB_ETS.sys, and mbtusbser.sys were the incompatible drivers. After looking throughout the forum here, I was able to remove the first two using the cmd prompt method. The mbtusbser.sys was not listed however. I was able to find it by searching in the File Explorer. It was listed twice so I deleted both and reset the computer. When I tried to turn on Memory Integrity again, I got the same "Resolve any driver incompatibilities and scan again" error. However, when clicking "Review incompatible drivers", there are no driver incompatibilities listed.

I have tried a few more suggestions and at this point am just messing around with stuff that I probably shouldn't be. Does anyone have any fixes for this?

 

Memory Integrity Won't Turn On

Thanks for your reply.

I've joined the Windows Insider Programme and updated my laptop to 22H2 as this appeared to be the only thing listed that I didn't currently have. It's installed, but when I tried to switch on Memory Integrity from the settings it still scans for incompatible drivers, doesn't seem to find any and then says it needs to restart. And again once I press restart it gets to the Medion logo (just before the windows screen appears) but just hangs there.

On the suggestion you've linked above, Option 2 is "Refresh or Reinstall Windows Defender". Now if I follow this step and delete the Windows Defender folder in the registry as suggested, do I need to reinstall or will Windows do this automatically when I restart? I don't want to go deleting the folder and then finding that I've shot myself in the foot so to speak.

**Update**

I tried Option 2 and unfortunately this hasn't worked either, my laptop still hangs on the Medion logo without loading Windows after reset. I have to hold the power button to turn off and restart, then it loads Windows succesfully but still with Memory Integrity off.

Option 3 doesn't seem to be the problem as it's not detecting any incompatible drivers.
