      Win10 Pro 1903, up to date as of Jan 2020

      I am also running Norton Internet Security and Malwarebytes Premium, and Windows Defender is set to OFF with respect to periodic scanning.

      I have NAS storage, and whenever I drag and drop from the NAS folders to my laptop, or even between the NAS folders, a Windows Security popup shows up stating “These files might be harmful to your computer”.  I can click OK and the warning goes away.

      As per information I found when this started happening, I these NAS drives as Exclusions in Windows Defender.  I confirmed they were added by looking at the Windows Defender registry keys.

      However, I still get the popups every time.

      I also temporarily added the drives as exclusions in Norton and Malwarebytes, but that also did not stop the Windows Security popups (as I expected… why would it?… the problems is with Windows itself).

      As I said, I can click OK when the popup shows up, but it is a hassle doing it every time.

      Since nothing I found using Google works, I thought I’d ask here.

      Is this a known “bug” in Windows?  Is there any workaround?

      Are you adding the target folders to the exclusion list?

      If the NAS is accessed by IP address, it may need Local Intranet settings in Internet Options:

      Disable “These files might be harmful to your computer” on Windows (YouTube video)

      (I.E. Not Windows Defender-related)
