Windows 10: Windows Defender deleted my download without permission

I downloaded a large archive from Edge browser, but the file was deleted immediately after finish. It says virus detected and there is NO WAY to restore it! Now I have to waste another 3 hours to re-download that file! Is this a bug or design issue? If not, could someone tell me how to stop this without turning off Windows Defender?

:)

 

Unable to delete a folder - Invalid folder name


Suggestion:

1. Run chkdsk x: /r to make sure that there's no HD corruption.
   x: is the drive containing the folder you want to delete.
2. Try to delete the folder again. If still does not work, go to step 3.
3. Download: Download - Linux Mint and create a bootable USB using: Rufus - Create bootable USB
4. Boot up with Linux Mint and try to delete the folder again.
   NOTE: Unlike WinPE. Linux does not have any Windows permission imposed to it so it is easier to delete.

 

File permissions to delete file

I am trying this, but it's taking a very long time.
