After some spyware changed my background, I was able to delete it with a series of anti-spyware tools and anti-virus tools. However, my background won't appear when I'm using my computer. When I reboot, I can see it, but then it is covered by a plain grey screen (I can change the color, just not the background image). I've tried going to Desktop Properties and unchecking the sites in the Web Browser under Advanced, but nothing was checked. I still can't change or see my background (other than the brief seconds of shutting down and starting up). Does anyone know what the problem is?
