Ok, I accidently clicked yes on a popup. It changed my desktop to a blue background and is just a big advertisement. At the very top I can see the colors of my real background. It's like an application is just sitting on top, and I can see my icons and click them and whatnot. I've ran adaware, I tried alt+ctrl+delete and closing it. Nothing works. Please help! p.s. - It is an HTML document.
