If you check out other threads on this forum about this, you'll find that the code referred to will work in early versions of IE 6.0 because it had a bug in it (called an "exploit" by Symantec - the Norton Anti-Virus people) that would let a web page run applications, including formatting the hard drive, without user permission. That has since been patched, so you can't count on it for anything. It's also dangerous because if YOU are using a copy of IE that has that bug, malicious code can do anything to your computer the web programmer wants.
