I did not trust into the firewall successfully blocking games to access the web, too, like you, but learned meanwhile that it reliably does that. You can leave it to the automatic learning, just deny any requests in popup windows, and after some time your major software pool is covered, and you have your peace then. and really - no need to spend the time working so hard with it. Leave it to the software, and it will serve its purpose.

I meanwhile got the impression that Comodo really outshines Zonealarm, at least the free version of it.

If you spend the time nevertheless, do not forget to export and save your settings and options afterwards to an external file. There is an option for that somewhere. Else you need to do it again when reinstalling your system.
