We've used Windows Defender for Linux systems for quite some time (simply by allowing access to the remote filesystems) and we have been positively surprised that threats for Unix/Linux-only systems are caught just as fast, even though there is no official support outside of Windows thus far. However at the time almost all of the malware definitions are from other anti-virus companies and Microsoft happens to ship them via Windows Update. But this could have been changed by now. If Microsoft is serious about the 'user-centric' approach, which it seems more and more the case as opposed to just a cheap PR stunt, it might me a good move to opensource the whole Defender base and include some Linux users while their at it.
