I had AVG internet security 2011 version, until I've installed the 2012 version, which is non-free/paid version/free for a month. Today it has expired, and I want to return back to the 2011 version, which was free. I don't want to download it and reinstall it, because then I have to reset all the settings; as long as I remember, during the install of the 2012 version, I was suggested to return to the 2011 version, if I wanted to. How can I do that? Thanks!
