I have both - for the paid version you will get full technical support and they are really very helpfull and fast with replying. It is for a 2 year period - then you have to renew again.
I downloaded AVG 7 directly from them as they had given me a link and burned the file onto a CD - I just found out, you can also order via their on-line shop - have a look here:

The paid version (7) also has more bells and whistles.
i use the free version would i be better off paid and can you get cd to install same?
