Description

This policy setting allows you to specify an interval at which to perform a quick scan. The time value is represented as the number of hours between quick scans. Valid values range from 1 (every hour) to 24 (once per day). If set to zero, interval quick scans will not occur. By default, this setting is set to 0. If you enable this setting, a quick scan will run at the interval specified. If you disable or do not configure this setting, quick scan controlled by this config will not be run.
