Everything is gone, my background, the Start button, date time in the right hand corner, the entire task bar at the bottom of the screen. I have uninstalled the AVG update and restored to just prior to the update but everything is still gone. I can access the desktop from the My Documents folder that opens upon entering the password to my user account. ( It never opened this way before.) The "desktop" screen is completely black and I have tried the Right click on the desktop to get to personalization but that doesn't work, it doesn't even respond when I right click. When i right click from the My Doc folder that auto opens I don't get a personalize option. Please HELP!!
