SmartScreen Filter was already off, but this is not an IE issue, since I'm not even using IE. I am using Comodo versions of Chorme/Firefox, Comodo Dragond and Comodo IceDragon, and with both I am getting the same virus warning error.. then windows defender deletes the file...
I think its more a windows defender thing.. I dunno but Windows 10 acted really strange today after an update, got multiple messages from it changing my default programs to use again the Microsoft apps.. again... #$%^&* Microsoft... so I don't know if its because of this update or not.. but it is definitely a Windows 10/Windows defender thing..
Edit: OK, for some reason it worked with Microsoft Edge.. I haven't tried with IE.. so I guess in a way for me this problem was solved..
