- In Active mode, Microsoft Defender Antivirus is used as the antivirus app on the machine. All configuration made with Configuration Manager, Group Policy, Intune, or other management products will apply. Files are scanned and threats remediated, and detection information are reported in your configuration tool (such as Configuration Manager or the Microsoft Defender Antivirus app on the machine itself).
- In Passive mode, Microsoft Defender Antivirus is not used as the antivirus app, and threats are not remediated by Microsoft Defender Antivirus. Files are scanned and reports are provided for threat detections that are shared with the Microsoft Defender for Endpoint service. Therefore, you might encounter alerts in the Security Center console with Microsoft Defender Antivirus as a source, even when Microsoft Defender Antivirus is in Passive mode.
- When [EDR in block mode](../microsoft-defender-atp/edr-in-block-mode.md) is turned on and Microsoft Defender Antivirus is not the primary antivirus solution, it can still detect and remediate malicious items.
- When disabled, Microsoft Defender Antivirus is not used as the antivirus app. Files are not scanned and threats are not remediated. Disabling/uninstalling Microsoft Defender Antivirus is not recommended.
- When disabled, Microsoft Defender Antivirus is not used as the antivirus app. Files are not scanned and threats are not remediated. Disabling/uninstalling Microsoft Defender Antivirus is not recommended in general; if possible, keep Microsoft Defender Antivirus in passive mode if you are using a non-Microsoft antimalware/antivirus solution.
