Don't install Zone Alarm. It can cause your internet connection to stop working and is a pain to fix. There are several documented issues with it and to fix it is a total pain. They used to have some of these issues and fixes documented at their site but pulled them. One of their reps told me that the only fix for one of the problems was a reformat and reinstall of the OS because they were never able to trace the problem.
