Windows 10: Windows Defender stopped!

Windows Defender stopped working on my Windows 10. How do I get it started again? I have never had another virus app on my computer. The settings option to turn it on is grayed out. I've tried everything that was recommended, including register tweaks and group policy changes to no avail. Help!
