I know with my dial up connection I cannot possibly download the free 5.0 version.
52 some MB and would take 14+ hours to do so.
Guess I'll have to switch to AVG now.
As has been said even the avast installation file is comparative at the least and smaller than many other AV installation files. AVG 9 installation file is almost twice the size of avast5 free multi-language version and over twice the size of the avast5 free English version installation file, see image.
This link (see below) it to the English language (only) version and not the multi-language installation version and weighs in at around 42MB, still a long haul on dial-up, but not as bad as some.

Have you tried using a download manager, at the very least you can resume where you left off it needs be. Have you got a friend with broadband that can download it and burn to CD or USB. Have you got a local library or other public service with broadband, etc. and download it from there.
I have only very recently got broadband (very slow 256Kbps) 9 days ago and before that I got on with avast on dial-up for over six and a half years. That was when I abandoned AVG and I haven't looked back,
