This article explains how to turn Microsoft Defender Antivirus Real-time Protections in Windows 11 on or off.
Microsoft Defender Always-on protection consists of real-time protection, behavior monitoring, and heuristics to identify malware based on known suspicious and malicious activities.
Always-on (Real-time protection) is enabled by default and turned on in Windows 11. When enabled, the always-on feature monitors events such as file processes, file and registry changes, and other events on your devices for suspicious and known malicious activity.
Microsoft Defender’s Real-time antivirus protection will also automatically scan downloaded files and attachments. Turning off real-time protection drastically reduces the protection on your endpoints and is not recommended.
If you turn off Real-time protection, you will see a red alert in the Windows Security app under Real-time protection, alerting you to re-enable always-on protection to keep your device secure.
