Information

This policy setting allows defining the number of days that must pass before spyware definitions are considered out of date. If definitions are determined to be out of date, this state may trigger several additional actions, including falling back to an alternative update source or displaying a warning icon in the user interface.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 14 days.

If this setting is enabled, spyware definitions will be considered out of date after the number of days specified have passed without an update. If this setting is disabled or not configured, spyware definitions will be considered out of date after the default number of days have passed without an update.

Solution

Set the policy value for Computer Configuration >> Administrative Templates >> Windows Components >> Windows Defender Antivirus >> Signature Updates >> 'Define the number of days before spyware definitions are considered out of date' to 'Enabled' and select '7' or less in the drop-down box.

Do not select a value of 0. This disables the option.
