This tutorial will show you how to add or remove the "Scan with Microsoft Defender" context menu your account or all users in Windows 10 and Windows 11.
Microsoft Defender Antivirus is an antivirus software that is included in Windows 11 and can help protect your device from viruses, malware, and other threats.
Microsoft Defender Antivirus regularly scans your device to help keep it safe. It tries to do this while you are not using your device so it doesn’t interfere with your work.
Real-time protection consists of always-on scanning with file and process behavior monitoring and heuristics. When real-time protection is on, Microsoft Defender Antivirus detects malware and potentially unwanted software that attempts to install itself or run on your device, and prompts you to take action on malware detections.
Sometimes you may need to manually scan with Microsoft Defender Antivirus. You can use the "Scan with Microsoft Defender" context menu when you right click on selected file(s), folder(s), and/or drive(s).
