locate the following registry key: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System delete the entry that lists a desktopWallpaper - most likely desktop.html (or .htm) You also need to run a full spyware and virus scan (get rid of spysherrif, nail.exe etc) and delete any .vbs files residing on the root of C:/
