That dial-up connection will take a while.

This site may explain it more;

The relevant part is "It takes between 7-10 minutes to download a one megabyte (1024 KB) file using the average dial up internet connection". An average dial-up connection is usually 56.6 Kbps.

A downloader won't help you with this. Whilst it may help re-establish a download it the connection is broken, it will not speed up your connection.

Can you get someone with a faster connection to download AVG8 for you and burn it to CD or load it onto a flash stick, or something?
