WNDF-AV-000058 - Microsoft Defender AV must enable extended cloud check.

Information

When Microsoft Defender Antivirus finds a suspicious file, it can prevent the file from running while it queries the Microsoft Defender Antivirus cloud service.

The default period that the file is blocked is 10 seconds. Extending the cloud block timeout period can help ensure there is enough time to receive a proper determination from the Microsoft Defender Antivirus cloud service.

Solution

Set the policy value for Computer Configuration >> Administrative Templates >> Windows Components >> Microsoft Defender Antivirus >> MpEngine >> Configure extended cloud check to 'Enabled' with a Policy Option value of '50'.
