Windows 10: Windows Defender and USB flash drives

Ive read that Windows Defender doesn't automatically scan any attached removable drives such as USB flash drives when a Full Scan is performed.
If that's correct. Lets say that you insert a USB flash drive that has somehow become unknowingly infected with malware. How does Windows Defender detect it and keep it from infecting your PC if it doesn't scan this flash drive immediately when it is inserted into a USB port on the PC?

Windows Defender scanning USB flash drive in the background


Hi guys,

Whenever I stick my USB flashdrive in my notebook, for some reason it will not paste my files there. The progress bar just says 0% when copying from my Documents folder and pasting to the USB stick. But sometimes. Especially when I leave the USB stick in for several minutes. And these are not huge files.

My assumption is, that its got to do with Windows Defender taking over the USB contents and scanning it and when its scanning the contents of it, it will prevent writing to the USB flash drive. Now, not saying that this is true, but I do have a strong feeling. And sometimes, it will have a delay to safely remove the USB flash drive as well.

So my question is, is there anything that I can do to prevent this from happening?

The scanning of removable drives is DISABLED or NOT CONFIGURED in Group Policy, so I have not even touched that.

How can I prevent the scanning thats happening automatically in the background without actually disabling Windows Defender?

What I can perhaps do, is adding the USB drive to the Exclusion list.
For example, adding D:\

Or maybe its scanning the Documents folder?

Any other suggestions?

Thanks
