Google's Google Pack is a set of software that you can choose from, and then google uploads an exe file to you that will automatically download the software you chose and install it. My personal software group contains the google desktop software, the google toolbar for internet explorer, the google talk instant messaging client, Mozilla Firefox, Norton Antivirus 2005, Ad-Aware SE, and Adobe Reader 7. In order to select your own set of software, go here.
