I wasn't paying attention to my downloads and unloaded some nasty spy/adware on my computer. I think I've got most of it weeded out, but I can't get my desktop to return to normal. It's always white. The wallpaper tries to load from time to time, but it always goes white. Also, there is an Internet Explorer window kinda overlayed into the top left corner that I cannot close. Has anyone seen this or know a solution?
