Subject: A worm...

Unfortunately, Microsoft is now including an unzipper program in their
OS (XP), so it's much easier for a lay user to make a mistake.  It used
to be that if you wanted to deal with zip files you needed to download
WinZip, PKZip or something similar, but now, thanks to Microsoft, all
you have to do is double click.

Mind you, it will *still* prompt you for a location to put the archived
files and you *still* have to go get those files and double click on
them to run them.  It's just a bit easier for the novice to get to them
now.
