I have a very similar problem. WindowsXP. DSL internet connection. When I attempt to install AVG Antivirus Free Edition (for the first time - I've just removed Norton360 prior to install of AVG), the installer stops with a 'Connection issue' - The AVG setup is not able to detect a working internet connection. Please make sure you are connected.....I am connect, and I even have another internet window open on www.avg.com - the site I believe it is looking for. If I save the installer first, and then run it from my hard disk, I get the same problem, although you can get it to install, but ofcourse you cannot register or get any updates, and in my case my internet connection then stopped working for some reason. I uninstalled AVG to get me back to where I am now, with a working internet connection, but no virus protection, and this odd installer error with AVG Antovirus Free - can anyone help?
