I had the question of if the Microsoft Surface Pro and Microsoft Surface Go running windows 10 with ARM processors. Is there any antivirus that supports this architecture without emulation?

A: The answer is not really as of 10/27/2021. Windows Defender will be your best bet at this time.

List of unsupported antivirus:
-ESET (emulation only?)
-Kaspersky (emulation only?)
-Trend micro (emulation only?)
-Norton
-Webroot
-Emsisoft
-Avira
-Avast
-Malwarebytes cloud
-AVG
-Sophos
-McAfee
-Bitdefender

Not to mention that even Google is behind in making sure its apps are compatible with the new wave of ARM processors. Google Drive doesn’t work on the Surface or the Go currently through the desktop. You’ll have to use the web GI to access your cloud files.
