About this Issue

Built-in Windows Defender is used to protect your computers from viruses, malware, and other threats. However, it is not always possible to get access to this program. This applies to cases where the user has installed a third-party antivirus program and it is incompatible with Microsoft's built-in antivirus.

  • Unable to Start Windows Defender Group Policy;
  • Group Policy Blocks Windows Defender;

  • Windows Defender Was Stopped by Group Policy, Group Policy is Not Working.

This article will help you deal with these errors and get the built-in Windows Defender to work properly.

1.1. Third-Party

First make sure all old third-party antivirus tools are removed.

Windows Defender is almost always automatically disabled after installing another antivirus. Perhaps this is your case and removing the antivirus will help you cope with the problem. Sometimes, simply uninstalling the program is not enough, as some files or registry entries may remain. It is they who will interfere with the work of Windows Defender, and you will not understand what the matter is.

Therefore, it is important to remove these files from your computer using a dedicated tool for removal.

If you have done all this and the problem persists, you should switch to another third-party antivirus software. This solution will be even more relevant if you need advanced features such as online banking protection or privacy insurance.
