Welcome to the forum brianitos, i sympathise with the way your feeling, i spent many a sleepless night worrying and generally feeling ill at ease because i was using a free firewall. It was only after many sessions with my councillor (an I.T colleague at work) that i finally came to terms with what i had done, my only advice to you is that the old saying that nothing in life is free is true and that Comodo is the exception to the rule.
Chill brianitos, safe in the knowledge that your PC is protected by the finest (and yes it's free!) firewall.
