Disable: 'Configure local setting override for schedule scan day' This policy setting configures a local override for the configuration of scheduled scan day. This setting can only be set by Group Policy. If you enable this setting, the local preference setting will take priority over Group Policy. If you disable or do not configure this setting, Group Policy will take priority over the local preference setting. Counter Measure: Configure this setting depending on your organization's requirements. Potential Impact: If you enable this setting, local settings will override Group Policy and may not be as secure as the Group Policy settings.
