Since I have started using BitDefender 9 Standard again, and my subscription is coming due in March, I've been thinking about BD 9 Pro. I am using it along with ZoneAlarm Free. I would like to know from any BD Pro users, how good is the firewall. How would you compare it to the stand alones like ZA? Is the firewall worth the extra money, or should I just stay with BD Standard and free ZA? Money is not a problem, I just don't want to pay for something that is not as good as what I'm using.
