Path in the GPO console
Computer Configuration\Administrative Templates\Windows Components\Microsoft Defender Antivirus\Security Intelligence Updates Description
This policy setting allows you to define the number of days that must pass before spyware security intelligence is considered out of date. If security intelligence is determined to be out of date, this state may trigger several additional actions, including falling back to an alternative update source or displaying a warning icon in the user interface. By default, this value is set to 7 days. If you enable this setting, spyware security intelligence will be considered out of date after the number of days specified have passed without an update. If you disable or do not configure this setting, spyware security intelligence will be considered out of date after the default number of days have passed without an update.
