I have installed zone alarm because I need a stronger firewall. What else does zone alarm do? After installing it and running it, the program changed my network settings and stuff, and it won't let me connect to the internet. When I quit the program, then it will let me connect to the internet. How do i configure the program so when I load zone alarm, it won't change my network settings, and be able to connect to the internet? Hope you know what I mean. In my computer I have norton internet security 2002 installed and it has expired a long time ago (it came when I bought the computer). Does the firewall still work although it has expired?
