Exclude the Controller data directory (<controller_home>\db\data), or simply the entire Controller directory, from scanning by Windows Defender. If you are not sure whether Windows Defender is running on the system, check for it in your local Services list. You can either configure the Controller data directory to be excluded in the Windows Defender Control Panel, or disable the service altogether if it is not needed.

For details on how to view services and exclude directories in Windows Defender, refer to the documentation for your version of Windows.
