Random Code and Legacy Widgets

I logged into my site last night and it was a horror show. There was junk code in the sidebar instead of the widgets I had set up with menus and tables. I think I got rid of most of it, but the bigger problem is the code written all over the bottom of the page. I don’t see any identifying strings that would tell me where it is being generated. I tried changing themes with the same result. None of this was here the last time I logged in about 3 weeks ago. Was there an update that I missed?
