1: Turn on "Warn before launching Classic." via System prefs 2: Uncheck OS X Safari's "Open Safe Files After Downloading" in Safari prefs. 3: Uncheck both Classic Quicktime's "Enable Audio CD AutoPlay" and "Enable CD-ROM AutoPlay" To do this: Launch Classic via the System Pref's and check "Show Classic Status in Menu Bar" In the "9" menu, select Apple Menu Items>Control Panels>Quicktime Settings>AutoPlay Uncheck (turn off) both "Enable Audio CD AutoPlay" and the "Enable CD-ROM AutoPlay" Quit Classic. This will make your computer less prone to exploits. Apparently a web site can download a volume with a application right to your computer just by visiting it. The novice could open the application and launch destructive code or it could auto-launch taking advantage of Classic Quicktimes Auto launch feature, as the AutoStart worm did. Most likely this exploit has been fixed, but having a volume and a application within easy reach of a novice can't be good.
