Each entry must be listed as a name value pair. The name defines a threat alert level. The value contains the action ID for the remediation action that should be taken. Valid threat alert levels are: 1 = Low 2 = Medium 4 = High 5 = Severe Valid remediation action values are: 2 = Quarantine 3 = Remove 6 = Ignore

Click the "Show…" box option and verify the "Value name" field contains a value of "1" and the "Value" field contains a "2". A value of "3" in the "Value" field is more restrictive and also an acceptable value. Procedure: Use the Windows Registry Editor to navigate to the following key: HKLM\Software\Policies\Microsoft\Windows Defender\Threats\ThreatSeverityDefaultAction Criteria: If the value "1" is REG_SZ = 2 (or 3), this is not a finding.
Set the policy value for Computer Configuration >> Administrative Templates >> Windows Components >> Microsoft Defender Antivirus >> Threats >> "Specify threat alert levels at which default action should not be taken when detected" to "Enabled". Select the "Show…" option box and enter "1" in the "Value name" field and enter "2" in the "Value" field.
