    Windows 10 Windows Defender Security Center/Virus and Threat Protection


    Just this week I started receiving notifications that virus and threat protection was turned off. When I checked all the settings under virus and threat protection were turned off and when I attempted to turn them on I received a pop-up message:


    User Account Control


    Do you want this app to make changes to your device?


    Windows Defender Security

    Verified publisher: Microsoft Windows

    yes or no


    The "no" is selected by default and when I click on yes it takes me back to the settings with the virus and threat protection setting turned off. Any assistance on correcting this is greatly appreciated since I am not a technical person. Thanks

    :)

    Cannot turn on Windows Defender virus protection

    I had the same sort of symptoms. In the Windows Security Center, under Virus and threat protection, it said "Your virus & threat protection is managed by your organization."

    I note you mentioned the Registry Keys under HKLM/SOFTWARE/Microsoft/Windows Defender. Nice spotting, but it seems like there is another key that is causing the problem for some users.

    Steps to a solution:

    1. Press the Windows key and type "regedit"
    2. On the regedit icon that appears, right-click and select Run as Administrator.
    3. Navigate to the folder located at HKLM\SOFTWARE\Policies\Microsoft\Windows Defender (You can paste this into the address box at the top of the window, or navigate manually using the side directory structure)
    4. In this folder, there are probably two keys. Right-click and Delete the DisableAntiSpyware key.
    5. Exit regedit, and return to the Windows Defender settings screen (refresh it if necessary). Windows Defender should have the scan options available and working.

    Solution adapted from here, with a much more detailed solution here.

    Can not access Virus and Threat protection to run defender

    Hello,

    Open Group Policy snap-in by running gpedit.msc command.

    Go to Computer Configuration > Administrative Templates > Windows Defender Security Center > Virus and threat protection.

    Set 'Hide the Virus and threat protection area' setting to Not Configured.

    Let us know if this helps!

    Virus & Threat Protection

    There are some applications that are not yet compatible Control Folder Access. It is intended to block Ransomware. Until third party apps catch up, the best you can do is to disable it.

    Open Windows Defender Security Center

    Click Virus & threat protection

    Click Virus & threat protection settings

    Scroll down to Controlled folder access

    Toggle it off
