Genieo is an OSX Adware that could be posting as fake Flash Player alerts, or video codecs, to trick users to download and install itself without user interaction.
It would alter users' homepage and search engine settings to its own. Although an uninstaller is offered, it would still require manual uninstallion for a complete removal.
Sometimes the uninstaller might not be able to reset browser settings properly so it would require users to restore the settings themselves.
