Computer anti virus - AVG 10 2011 installation is slow because it needs internet connection

I've been installing new anti virus for my computer, the AVG 10 2011, year 2010 is still two months to go yet more anti virus vendors are releasing new anti virus for year 2011. The new AVG 10 anti virus is light, load up quickly. Even though the installation file is only 4.5MB, but during the installation process AVG anti virus will ask you to put the internet connection on, why? Because AVG installer file need to download additional installation files from the internet, so it makes installation process takes 35 to 45 minutes to finish up in my computer. AVG says in the website installation process for this new anti virus version will be fast, but in my experience of installing AVG anti virus last two days, installation is slow, updating its virus database may take additional 20-30 minutes.
