 When Windows Defender Antivirus is automatic disabled, it can automatically re-enable if the protection offered by a third-party antivirus product expires or otherwise stops providing real-time protection from viruses, malware or other threats. This is to ensure antivirus protection is maintained on the endpoint. It also allows you to enable [limited periodic scanning](limited-periodic-scanning-windows-defender-antivirus.md), which uses the Windows Defender Antivirus engine to periodically check for threats in addition to your main antivirus app.

 In passive and automatic disabled mode, you can still [manage updates for Windows Defender Antivirus](manage-updates-baselines-windows-defender-antivirus.md); however, you can't move Windows Defender Antivirus into the normal active mode if your endpoints have an up-to-date third-party product providing real-time protection from malware.
 
 If you uninstall the other product, and choose to use Windows Defender Antivirus to provide protection to your endpoints, Windows Defender Antivirus will automatically return to its normal active mode.
