Are you using WindowsSimpleHardening or Hard_Configurator along with CD? Try right clicking the icon and see if a Install By Smartscreen option is there or run as administrator. There are lots of browser options out there and if your using Microsoft Defender anyway, that's best accompanied with Chromium-Edge.You think I didn't try running the installer outside the browser immediately after?
If it's not MpEngine, then it's something from Windows 10, outside Defender.
