I am about to format a pc and decided to download the zone alarm set up file so that I will install it after finishing installing windows and before connecting the pc to the internet. However, I am noticing that the setup file I downloaded is only about 4.37MB. Is this the full installation file or does it require to connect to the net to install because older installation files had a larger file size?

The reason I am asking this is that I do not wish to connect to the net before having both a firewall and an antivirus installed.

Thanks for any feedback.
