I used to me a diehard Zonealarm fan.. for years. Then things changes there and not for the better. I went with Microsoft Security Essentials and a number of other free firewalls - I can't even remember all the ones I tried. I have to say that Online Armor has surpassed my expectations. It did not slow down my PC at all. I do have 4 megs of ram and if you're finding it's slowing down your system you really need to upgrade your system. I have it paired with Avast free antivirus and the two programs so far are living together harmoniously.
