Geekgirl - Hijacked: "Security holes in the major browsers make it necessary to bump up the security features to an annoyingly invasive level. Browser hijacking is the use of scripting tools to modify your browser?s default settings. This may be as trivial as adding a new link to your Links or Favorites or as unconscionable as changing your home page persistently via a combination of scripting, registry changes and auto-running programs."
