For anyone interested, I have decided to go with Kaspersky for the two main
computers at our shop.
Now, which fire wall is better: "free" ZoneAlarm or Comodo?
AND are they really free, or will they do pop ads, or expire?
Yes they are better than Xp's firewall, because they confront the user with
what he is doing and let him think before he allows a program to connect to
the internet or start another program.
I prefer Comod for its lesser use of system resources.
