Disable: 'Configure local setting override for the time of day to run a scheduled full scan to complete remediation' This policy setting configures a local override for the configuration of the time to run a scheduled full scan to complete remediation. 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.
