Once the link has been clicked - it will redirect you until it downloads a copy of itself. And if it's accidentally executed, it will disable your Task Manager and Registry Editor. Moreover, it will set your Internet Home Page, Yahoo Buzz link, and Launchcast link to hxxp://www.geocities.co.jp/tha[REMOVED].
Be cautious in clicking these links, especially with the above mentioned strings.
