I have downloaded Internet Security 2015 and tried to install it ten times over the past 20 hours. The installation is not able to complete and there is a message when I click on the URL that says AVG servers are down for maintenance. Why?

William, Try installing AVG Internet Security by downloading & using the appropriate either 32 or 64bit file, whichever suits your system, from this link (http://www.avg.com/ww-en/download) [Scroll Down / More options]. If you're not sure about 32 or 64 bit on your system have a look @ this link (http://forums.avg.com/ww-en/avg-free-forum?sec=thread&act=show&id=140471#post_140471).

Look all I want to do is install Internet Security 2015. I am a paying customer. The installation is not able to complete in spite of trying again and again and again and again.
