Windows Update Mistake Triggers False Antivirus Warnings

Microsoft has acknowledged that recent Windows updates have caused an issue where users are receiving warnings that 'Microsoft Defender Antivirus is turned off', despite the antivirus being fully functional.

The notifications, which can appear when Windows starts and intermittently afterward, have been triggered by the latest Windows antivirus updates. According to Microsoft, these notifications persist even if notification settings are turned off.

Users who see this warning should double-check that their Microsoft Defender Antivirus is running and real-time protection is enabled, as stated by Windows Latest. It's essential not to dismiss the alert without verification, as it may cause unnecessary worry in light of recent AI-fueled attacks and frequent Windows zero-day security threats.

Microsoft has assured users that the antivirus is functioning correctly and all settings show it as active. The company is working on a resolution to address this issue, which can be observed in any version of Windows or Windows Server with Microsoft Defender Antivirus running with the latest Defender updates.
