I paid for NSW av, and had so many probs with liveupdate etc, av not working that I went the free route. I've used AVG, Avast and now I use AntiVir Guard. For firewalls I paid for Zone Alarm and had so many probs I again went the free route and now use Kerio. It's horses for courses and many will have their own prefs. For Spyware I use SpyBot and Adaware which clears out lots.
