Ok so I was going through my horribly spammed Yahoo mail and was marking which emails to delete and which to keep. I accidentially clicked on one instead of marking it, and it opened up, followed by some error message. I closed everything and 10 seconds later some software was automatically installed on my computer (supposedly a spyware scanner), along with my homepage being changed to a web page file in my C:\ drive (which said "You have Spyware! Follow these steps.." blah blah blah. It also changed my desktop wallpaper and locked me out of changing it.

I have removed the files, done full scans for spyware and viruses, and even attempted to change my wallpaper through other means, and it does change, but this picture (shown above) keeps overriding it and masking whatever is there.

As you can see, everything inside the box (all the wallpaper options) is grayed out, and I can't select anything.
What the fack is going on
Edit: Ok I got the stupid wallpaper deleted, now it's just a white screen. But it's still locking me out from changing the wallpaper. =\
