I have ZoneAlarm Security Suite, and I like it pretty well. It won't bother you too much.....you only have to deal with the warning one time, and then you just click "remember this setting" when you tell it to allow the access. As far as the general protection notices, I just turn those off to "protect my computer silently". I used to think it was cool to see that it was blocking access to my computer and seeing whether it was high rated or not, but after a while I just didn't care anymore so I turned the notices off.
The Antivirus works well too.
You're gonna have people on both sides of the issue, just like anything else. As for me though, I'd recommend it.
