On Windows 10 with latest updates, I have a ZIP file in an AppData\LocalLow sub-folder:
From Windows File Explorer, whenever I right click on this zip file to open the context menu, I get a warning popup saying "Opening these files might be harmful to your computer":
The same ZIP file placed on my Windows Desktop doesn't trigger this warning, so it seems it has something to do with the AppData folder.
I've read this related post:
Disable "These files might be harmful to your computer" warning?
But my problem is not for a network copy and solutions described here does not work for my case.
