I accidentally went to this site after freshly installing Windows 7, and it immediately popped up a window claiming that the computer had malware, that I must not shut it down, and that I must call some Microsoft hotline for help. I doubt the hotline was actually with Microsoft. Since the popup window would not go away, I did Ctrl-Alt-Del and shut it down. If I find any malware or can't restart Windows, as the popup was claiming, I'll just reinstall Windows.
