How to manage Microsoft Defender Antivirus from Command Prompt on Windows 11

Microsoft Defender Antivirus is the default anti-malware solution that protects your Windows 11 installation and files from unwanted viruses, ransomware, spyware, and many other types of malware and malicious attacks.

Usually, you would use the Windows Security app to manage the antivirus, such as scanning, updates, and quarantined items. However, it’s also possible to control the Microsoft Defender Antivirus with commands from Command Prompt. For example, when you have to use a script to automate specific tasks. You are in charge of managing multiple computers, and you need a quicker way to run specific tasks. Or you want to schedule an update and scan at a particular time.
