Windows XP has a very serious flaw that is fixed in SP1 (Service Pack 1). If you havn't installed SP1 yet, have experienced SP1's sometimes nasty installation problems, or don't plan to install it for for some reason, Steve Gibson has produced a small utility that will protect your computer against the danger. Here is his page describing the problem and the free utility.... http://grc.com/xpdite/xpdite.htm It only takes about 5 seconds to take the download and it will also tell you if your XP system with a service pack is safe. There is an option if you get a "dangerous file is present" message to fix it to a safe file. I myself am waiting for more of the bugs to be worked out with the SP after the stories I've been reading. I found this little message on both of my computers after I took the download from grc.
