GRC.com: XPdite - Quickly replace a dangerous Windows XP file
Without XPdite, or XP's Service Pack 1, clicking on a simple, but malicious, URL can delete the entire contents of your directories.

This FREE 30 kbyte "XPdite" utility protects your Windows XP system until you are able to install Service Pack 1.

...

Again: EVERYONE using Windows XP, who has not already installed the huge (50 to 140 megabyte) Service Pack 1, is presently at risk of having many files maliciously deleted from their systems. PLEASE SPREAD THE NEWS of this critical Windows XP vulnerability -- and this quick and simple solution -- to everyone whom you know to be using Windows XP. If you or they have already installed Windows XP Service Pack 1, the problem has already been cured.

Otherwise, this small, quick, and free utility will handle the job easily.

Thank you.

Steve
