OK, most of us have routers that have firewalls. And many people still suggest having antivirus and firewall software. You can do what you feel is safe. But you're putting lots of faith in one area that is not known to be infallible. I just hope you don't have any troubles. As for Zone Alarm, I killed that years ago because it was not smart enough to know friend from foe. It thought my ISP's email server was an invader. I've sworn by Symantec products since 1995, and they have not failed me.
