Windows 10: Can't Turn On my Windows Defender Real Time Protection

For ages now, I've been unable to turn on my Windows Defender Real-Time Protection. I've tried everything including Disk Cleanup, system restore points, running several different antivirus programs for threats (after discovering last week I had a Trojan on my PC only 24 hours since my previous virus scan before that). I have always run a full scan every day or two for over a year now.
It says that it turns back on automatically after a short time, but it's been turned off for months now and no matter what I try, it won't come back on.


HELP!

Unable to turn on Windows Defender real time protection


Hi guys, I'm a bit desperate here right now. *Confused

I have the same problem that this guy over here. I'm running Windows 10 Home x64, version 1607, build 14393.0.

I had to restore the PC to a previous point because I ****ed up some drivers. Then my AV (Bitdefender Free) started having some issues (they gui didn't display correctly) so I decided to uninstall it and just go with Windows Defender.

The problem is I can't get it to work... I get a notification in the Action Center saying to turn on the virus protection, when I click it, Windows Defender goes green(PC status: protected, Real time protection: on) for a second and then goes yellow again (PC status: Windows Defender is OFF, Real time protection: Handled by another AV program) and I get the notification again. If instead of clicking the notification I click "Turn on" on the Windows Defender gui, Windows opens another window, "Apps & Features" in settings, like asking me to uninstall the other, nonexistent AV.

Now, I've tried a lot of things...

• Of course, I have completely uninstalled Bitdefender. I used the official tool provided by them for this. There is nothing in the registry by bitdefender nor any file or folder by that name in my PC.

• I have tried every step listed here.

• I have tried to install another AV (Avast) and the uninstall it to see if this would "reset" somehow windows defender. (Nope.)

• I have tried option #2 here Windows Defender - Turn On or Off in Windows 10 - Windows 10 Forums

• I have run MBAM and nothing pops-up

In HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender there is noDisableAntiSpyware key. But in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender there is a DisableAntiSpyware key and its value is 0. (Not sure if this is important but wanted to give you the info.)

Anyone has any idea? Right now I'm thinking of downloading another AV or just go without any and be done with it. *Huh

 

Windows Defender Real-time Protection will not turn on

I've done the exact same steps and same for me. Still won't turn on. Anyone have a way to muscle defender into turning on real-time protection?
