actually, I use windows 10, and there is such thing as bytefence, as it sometimes may go onto your computer without you knowing, as it did to me.
A solution may be to just uninstall bytefence.
This is NOT a "Duplicate". I am using windows 10, however, "bytefence" does not exist and is not blocking the download. Please reopen this issue as it is NOT resolved.
