Sheelagh, AVG Mac Free… That's the only version available. Have a look @ this article if you want to pursue a refund (http://avgclick.me/AVGRefundPolicy).

Thank you for the reply.  However having followed your link, it takes me to the Mac (free) download.  I have a paid for AVG still running, but when I log into my account I cannot get to the change to Mac type screen.  How do I do this please?
