@Handian Sudianto Apologies for the delayed response, from the above conversation I see you your are looking for PowerShell command which can provide files scanned information.
Researched on the PowerShell cmdlets available for Windows Defender - https://sid-500.com/2023/05/30/administering-windows-defender-with-powershell/
Though we can perform scan from the PowerShell, however it doesnt provide the output results in the PowerShell screen, it can viewed via GUI like you mentioned above.
Also, its not possible get this information via event viewer as well, reviewed the events as well - https://learn.microsoft.com/en-us/microsoft-365/security/defender-endpoint/troubleshoot-microsoft-defender-antivirus?view=o365-worldwide
Any specific reason why you are looking for this information via PowerShell.
Let me know if you have any further questions, feel free to post back.
