So I tried to download the latest iso from the website and Windows Defender says the file contains this bad boy. I don't even get to open the file, it just stops downloading and shows a pop up message. Is it a false positive?

mtldr_install.exe is just mtldr bootloader installer, not a virus or something like that. Antiviruses are stupid and assume many programs written in assembly as malware
