Windows 10: Black Bar across desktop background

Yesterday my wallpaper suddenly was half black on the bottom. It's worked for years but now it doesn't. I recently changed my second monitor, but this happened on my primary. I've restarted many times with no change, except that today the wallpaper is 3/4 black, only being able to see the top quarter. Any ideas? This is super weird.

Lost desktop background

I did a Search & Distroy spyware scan the other day, and one of the suggested "fixes" said something about removing Active Desktop. Like the muppet I am I clicked yes and am now without a desktop background picture.

Does anyone have an idea how to reverse this? If I try to select a picture it's simply not added as a background.
