Windows Defender broken, MalwareBytes install blocked

[AJNeuro]

Hello.

I was trying to install Malwarebytes but it seems whatever I've caught is blocking me from installing it since I get a message that the Admin has blocked it, but I am the only Admin. I also noticed a new process in my Task Manager that keeps popping up every one in a while even when I delete it, and a file in my Windows folder that also keep re-appearing when I delete it in safemode. My browser (firefox) is now riddled with ads that don't get blocked by uBlock Origin, and I notice that when I click on links sometimes they get parsed through some website. I also know I am infected because Windows Defender went ballistic with trying to block and quarantine files before finally collapsing, and now it won't turn back on again.

Any recommendations?

Oh I also forgot to mention; I ran MSERT (Microsoft Safety Scanner) and it picked up 4 objects but I'm not even sure it did anything.

Had the exact same problem for about an hour ago.

This thread helped me fix it:

Deleting my temp files did not work. I wasn't allowed to delete a few of them.
