You say you are not connected to the internet. You don't make clear if this is by choice or not.
If it is by choice, and if your system is cut off from everything else - ie you're not borrowing dodgy disks, then you don't need AVG 8.0 or the spybot programs. In fact you should consider turning off all the programs that are used to manage internet use.
If you do want to be connected, you should focus on that first. Presumably you have an ISP. The first line of help would be to contact them to arrange a connection.
