Innuendo Ariva(when you config tick the box expert mode) is a lot better at the false postives then B-4.I test them all right now I'm test Norton internet security and they have also gotten better.But you are right about unistalling thiings you better know what you are doing !!

Also here is Matousec Firerwall Testing Updated for June
http://www.matousec.com/projects/proactive-security-challenge/results.php
I guess that now it makes sense to test such products. Now the challenge is called "Proactive Security Challenge". So, not only dedicated to firewall testing, even though in the past firewalls + hips were tested, against those who are pure firewalls.
But, I believe that results shouldn't be mixed.
For example:
Online Armor Personal Firewall 3.5.0.14 is 1st. But, it includes firewall + HIPS.( I run this one From A Free Lic # from GAOTD)
ESET Smart Security 4.0.417.0 is 24th. I know it doesn't include a HIPS.
But, looking at those results, does it mean that ESET Smart Security has a firewall necessarily worse than Online Armor's? (I'm not saying one is better than the other, and vice-versa. Only that what can a random visitor think of such results?)
Truth is, as a firewall, Eset's could be much better than Online Armor. The only problem is that it has no HIPS. So, it won't, from a start point, even reach a near result.
I believe Matousec should make tests for:
Firewalls
Firewalls + HIPS
HIPS
Behavior Blockers
Not mixed all.
