I ran Spybot and it found PSGuard and AV-Gold. It removed PSGuard but asked for a reboot. Once I rebooted Spybot ran again before Windows could load and removed AV-Gold. But when I exited Spybot after the removal I found that my wallpaper is now tan and when something is open it turns white than back the tan. I tryed changing the wall paper but nothing happened. How can I fix this problem?
