I've gone through numerous threads on this site to try and fix my computer. My desktop was hijacked. I tried searching for desktop.html in hidden files and folders - nothing. I tried going to Properties => Desktop => Customise Desktop => Web => dead end - nothing. I've tried everything that's been suggested. I've had a blue, blank screen for almost a month now. I can see my regular desktop picture for seconds when I'm logging on or off. Can anyone help me?? I'm officially begging.
