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 is turned off

Hi Ahmed,

Since you're not able to turn on Windows Defender as well, we'd like to know if you have made any changes recently prior to this issue. In the meantime, you may follow the steps below on how to turn on Windows Defender manually:

• Type Windows Defender in the Search bar and press
  Enter.
  
• Go to Settings and make sure that the Turn on real-time protection recommended option is turned on.
  

Same thing with the other members who are having the same issue, we suggest that you check if the service was setup to
Automatic in the Services option. Please follow the steps that we've provided last
September 3, 2017.

Let us know how if you were able to turn it on properly by changing the Startup type to Automatic.

 

Windows Defender Real-time Protection will not turn on

Did you follow the steps recommended in Solutions : Support



How about the steps recommended at http://www.bitdefender.com/uninstall/



Try running the removal tools for any security program that you previously used on the computer and be sure to reboot after using each tool. See
List of
anti-malware product removal tools



Go to Security and Maintenance, look in 'Security' and see what program is listed under Virus Protection. Windows Defender will not be enabled if there is a program other than Windows Defender listed.



Have you tried the steps recommended in Problems
starting Windows Defender in Windows 8/8.1/10?

For further detailed information suggest you review the reply of quietman7 in
this thread: Windows Defender.

“The inability to turn on Windows Defender 8/10 is typically the result of having a third-party anti-virus installed or failure to remove it properly (completely). Since Windows 8/10 Defender includes anti-virus protection,
it is disabled during the installation of another anti-virus program. If a trial anti-virus (i.e. McAfee, Norton, etc) came preinstalled on your computer or you installed one, Windows
Defender will be turned off (disabled). Windows Defender recognizes the install and automatically disables itself when other anti-virus products are used to avoid conflicts. Windows Defender will remain
disabled until that anti-virus software has been completely uninstalled. In some cases, you may need to download and run the anti-virus vendor's clean up tool to remove any remaining remnants.

After removal of the third party anti-virus, Windows 8/10 Defender needs to be activated if you choose to use it. When uninstalling the third-party anti-virus Defender should automatically turn itself on but sometimes you may receive a message
indicating your system has no protection...click here to turn on Windows Defender. If not, and Defender remains disabled, you will need to manually turn it on.

If that is not the case in your situation, check to make sure the Windows Defender service
is started.

• How to Configure Windows Defender in Windows 8, 8.1 and 10 <- scroll
  down to "Couldn't start the Windows Defender service" error message

Sometimes it may take a couple of computer reboots after performing the above steps to ensure Windows Defender is up and running properly.”
