Installing antivirus on a notebook

This is a very basic question, but I’m new to this so…  I have purchased a AntiVirus 2009 for my son’s new notebook, which does not have a CD drive.  Before I break the plastic on the box I want to know if I can install it via our Mac.  Or do I need to download from the internet using his laptop?
