WNDF-AV-000003 - Microsoft Defender AV must be configured to automatically take action on all detected tasks.
This policy setting allows Microsoft Defender configuration to automatically take action on all detected threats. The action to be taken on a particular threat is determined by the combination of the policy-defined action user-defined action and the signature-defined action. If this policy setting is enabled, Microsoft Defender does not automatically take action on the detected threats but prompts users to choose from the actions available for each threat. If this policy setting is disabled or not configured, Microsoft Defender automatically takes action on all detected threats after a nonconfigurable delay of approximately five seconds.
Set the policy value for Computer Configuration >> Administrative Templates >> Windows Components >> Microsoft Defender Antivirus >> 'Turn off routine remediation' to 'Disabled' or 'Not Configured'.
