A nasty thing called "install.mac" has hijacked my Safari address bar search...
Yesterday I started trying to install Internet Explorer and a thing called DJVu in order to download a washing machine manual (I know...) and now my Safari and Firefox have both been hijacked by 'Install.mac' which I believe is a Genieo product. When I type a search into the address bar of either Safari or Firefox it automatically redirects to an Install.mac results page rather than Google. I can't find any evidence of either install.mac or Genieo anywhere on my mac in order to uninstall it. It seems to be hiding somewhere. Has anyone had the same experience and managed to get rid of the unwelcome guest?
