When I go into "Display Properties" to change the background, three of the usual buttons are missing, i.e., "Background," "Appearance," and "Web." The other buttons (Screen Saver, Effects, and Settings) are still there.
Question: How can I restore the missing buttons, especially "Background"? I am assuming that the infection removed the missing buttons, and that if I can restore them, I can get rid of the blue background with error message.
Thanks much
