Option 1 – Make sure that the Windows Defender Services are started

The Windows Defender Advanced Threat Protection service is the one that protects your computer from advanced threats by monitoring and reporting security events that happen on your computer. This is why you have to make sure that this, as well as other required services in Windows Defender, are set to their default values and are started. To do so, follow these steps:

  • In the Cortana search box, type “services” and click on the Services icon to open the Services Manager. Alternatively, you can also tap the Win + R keys to launch the Run prompt and then type “services.msc” in the field and hit Enter to open the Services Manager
  • After opening the Services Manager, look for the following services and make sure that their Startup type is set to their default values:
    • Windows Defender Advanced Threat Protection Service – Manual
    • Windows Defender Antivirus Network Inspection Service – Manual
    • Windows Defender Antivirus Service – Manual
    • Windows Defender Firewall Service – Automatic
  • You can right-click on each one of the listed services and then select Start to start them.
  • And if some of the services don’t have their default values, just double-click on the Services to change the Startup types and select the correct option from the drop-down menu of the Startup type under the Properties box.
  • Next, set up the Startup type of these services to Automatic and then click on the Start button if the services are not running yet.
  • Now click on the Apply and OK buttons to save the changes made and then see if it fixed the problem or not.

Option 2 – Try modifying some entries in the Windows Registry

If the first option didn’t work in fixing the problem, you can try to alter some entries in the Windows Registry using the Registry Editor.

  • First, tap Win + R keys to open the Run dialog box.
  • Then type “Regedit” in the field and hit Enter to open the Registry Editor.
  • Next, navigate to this registry path: HKLMSoftwarePoliciesMicrosoftWindows Defender
  • From there, look for the “DisabledAntivirus” and “DisableAntiSpyware” DWORDS from the right pane and change each one of their values to “0”. On the other hand, if you don’t see any of these DWORDS, you can create them instead and give each one of them a 0 value.
  • To create a DWORD, simply right-click on any empty space and select New > DWORD. Then name them both as “DisabledAntivirus” and “DisableAntiSpyware”.
  • Afterward, set the value of the newly-created DWORDS to 0.
  • Now exit the Registry Editor and reboot your PC to apply the changes made and then check if it has fixed the error in Windows Defender or not.
