I have kinda a big problem. I uninstalled Bitdefender as my old antivirus, and I wanted to use Windows Defender in the meantime while I looked for a different Antivirus. Problem is, I can't turn it on. I get a screen like this:
Naturally I press start now (or turn on depending on the screen presented to me)
Then it's fine for a few seconds. After those few seconds pass, it goes right back to the old screen:
I can't figure it out for the life of me. I tried doing the sfc scannow command and it said it was unable to fix some corrupted files or something (maybe that's it?). Anyways, I don't get this. It just keeps turning off as soon as I press turn on (or in this case "start now"). I'd appreciate help because this is bugging me and does not seem good.
I uninstalled Bitdefender without much of a trace and restarted several times, but still nothing.
