A "worm" is a stand alone piece of software that duplicates itself. Although some people write worms with malicious intent, this worm is written as an example of what the AppleScript™ language can do. To turn off this worm, choose "worm" from the application menu and then "Quit" from the File menu, and remove the copy of "worm" in your Startup Items folder.
worm sits in the background, checking every few seconds to see what volumes are mounted. If something new has popped up, worm copies itself to that volume -- either into its Startup Items folder, when possible, or to the volume's main directory.
