We have received some reports regarding AutoIt.D and Agent.AXN spreading via Yahoo! Messenger. AutoIt.D and Agent.AXN pops up a message randomly selected...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 http:://www.geocities.co.jp/tha[REMOVED]....
