18.9.77.14 (L1) Ensure 'Turn off Windows Defender AntiVirus' is set to 'Disabled'

Information

This policy setting turns off Windows Defender Antivirus. If the setting is configured to Disabled, Windows Defender Antivirus runs and computers are scanned for malware and other potentially unwanted software.
The recommended state for this setting is: Disabled.

Rationale:
It is important to ensure a current, updated antivirus product is scanning each computer for malicious file activity. Microsoft provides a competent solution out of the box in Windows Defender Antivirus.
Organizations that choose to purchase a reputable 3rd-party antivirus solution may choose to exempt themselves from this recommendation in lieu of the commercial alternative.

Solution

To establish the recommended configuration via GP, set the following UI path to Disabled:
Computer Configuration\Policies\Administrative Templates\Windows Components\Windows Defender Antivirus\Turn off Windows Defender AntiVirus
Note: This Group Policy path is provided by the Group Policy template WindowsDefender.admx/adml that is included with all versions of the Microsoft Windows Administrative Templates.
Note #2: In older Microsoft Windows Administrative Templates, this setting was initially named Turn off Windows Defender, but it was renamed starting with the Windows 10 Release 1703 Administrative Templates.

Impact:
None - this is the default behavior.

Default Value:
Disabled. (Windows Defender Antivirus runs and computers are scanned for malware and other potentially unwanted software.)
