I posted this in the Hardware section, and wasn't sure if it would be better answered here:

EDIT : So I ran Trojan REMOVER and accidentally removed something I don't think I should have :

C:\Documents and Settings\Administrator\NTUSER.DAT

My computer restarted and my desktop background was gone, and eveything looked a bit different.  For example on the start menu, the whole left side of the panel is now blank, the minize/maximize/close buttons are about 2 x SMALLER.  It won't let me set a picture for my desktop background, not even by right clicking a pic off the web.  It forgot my default homepage, and WEBPAGES SEEM to take much longer to load, youtube videos not showing up.   I tried a System Restore a few times, and although it brought the computer back to earlier times, before the great mistake, it didn't fix the problem.

If it's part of the registry that's been deleted, isn't there a CD I can insert, a program from the NET I can download, or anything I can do to get it back?  

Thanks in advance!
Andrew

It may have been better off here, or in Windows, but the main thread is in the hardware section now, including the answers you've got.
So keep with that thread instead of making new ones.Thread locked here.
