Securing QuickTime Preferences
You should only download QuickTime movies from trusted, secure sources. By default,
QuickTime stores downloaded movies in a cache. If someone gained access to your
account, they would be able to see your previously viewed movies, even if you did not
explicitly save them as files. You can change QuickTime preferences to disable the
storing of movies in a cache.
You should not install third-party QuickTime software unless you specifically require
that software.
