i downloaded a registry cleaner and i believe it gave me a virus because now my background is blue and i cannot change it. it will not let me click on the options to change the bacground. i see that some other people on this site have had similar problems but i cant see everything that was written to them so that i can fix the problem. i already poasted a thread and noone wrote me back. so if noone can help me, then can someone tell me if i am doing something wrong, am i not poasting this right?

Please insert your Windows CD into the Drive. Go to Start -> Run and type sfc /scannow. Keep in mind there is a space between "sfc" and "/scannow". this should repair the problem for the time being.

Next, look below the image in my signature and you will see a link to the PCHF Prework. Please follow that link and follow the instructions.
