Avast! actually sends up rules as well as plain old signatures as part of the database updates. So what you can do with BB and Network Shield (advertised as a light IDS) activated has never been explored by Matousec. I don't know either, BTW.
Of course the first thing a conventional HIPS like Comodo tells their users who find they have problems with their own leak tests is "you are in the wrong mode, dummy". Like they tell Matousec, don't use the default (quiet) mode if you want good leak protection. Think of this test scenario: You have a product set up to maximize the number of situations that generate popups for unknowns. You are told before the test that all of the popups are malware. Question of the day (Security for Dummies): What do you need to do to maximize your score? (hint: The developer part is to add more popups to get one for each of the test cases). Harder question of the day (where the work is moving): How can you do this silently? e.g. how do you automate your HIPS without a godzillion FPs and still catch everything. You can count on whitelists, etc. but you still need to deal with the residue.
And in spite of all these good intentions, and tests against questionable threats, you had better have an imaging program and backup regularly, because the malware community is usually a step ahead of the security community.
