To reduce the possible number of interference please uninstall malwarebyte's anti-malware completely - not just disabling it. You have Bitdefender doing a good job, probably Windows Defender is still up because Bitdefender tends to keep it also enabled and you have Windows SmartScreen enabled.
Clear your Windows tmp folder, reboot your PC and please try again with the exclusions I told you about.
You mean you haven't checked option Numpad 1: Mega Favour/ Mega Money? Might be worth it.
