Seeing as some users here are using the COMODO Firewall Pro I decided to give it a go to maybe and hopefully improve the protection I had so far. After the free version of ZoneAlarm (which I thought was a good program) failed utterly to withstand even the first of 3 tests of
Comodo Parent Injection Leak Test Suite I removed that piece of junk and installed Comodo instead, and guess what - it is much better than ZoneAlarm.
So whoever uses the free version of ZoneAlarm - if you want a good protection you'd be better off replacing ZoneAlarm with Comodo Firewall Pro instead, especially since that one is free too.
