There are many claims that if you leave your security preferences at their default level, it will install itself without your express permission. And once on your system, it's gracious enough to reset your homepage to xupiter.com, forward all your searches to their search engine, download and automatically launch applications (like gambling applets), and blocks all attempts to set these back to normal. Removing it isn't trivial either - it automatically checks for updates upon reboot, where it constantly changes the registry settings it uses, making the jobs of spyware removal programs like AdAware or Spybot Search & Destroy much harder. No word yet if it collects and forwards personal data."
