A virus removed my wallpaper to a black screen, and using an anti-virus program didn't undo it.
So after using Avira, I then right clicked the image, and seleted Set as desktop background.
It doesn't change a thing.
When I right-click the wallpaper, and select personalize, under My Themes (1), it just has an unsaved theme with an all-black image, which is essentially my wallpaper. I think somehow whatever image was stored it automatically became all black and I can't change it.
Is there anything in regedit or so I can type to fix it?
Note that, this virus, it did things that the anti-virus didn't undo. For example, it changed all my files in all my folders to hidden (and not viewing hidden files), and so I just have to manually unhidden files folders at a time. Obviously, the anti-virus didn't undo that, so I think there's some property I need to fix to get my wallpaper back again.
