Page-jacking - When a few lines of software code, perhaps written in Java, are hidden on a duplicate copy of a legitimate Web site.  When somebody tries to go to the legitimate Web site, they end up being redirected to the illegitimate duplicate copy. It's the illegitimate site that has that hidden code and that immediately re-directs him/her to another Web site, often pornographic.  Typically it becomes difficult for the 'hi-jacked' visitor to leave the site he/she is hijacked to. If that's the case the surfer should close out their browser by pushing (simultaneously) the Ctrl, Alt & Delete keys, then clicking “end task” when the appropriate program is highlighted.
