Definitely took sometime, but at least they are looking into it already.
Hopefully they use this information to improve current v5.x of CIS (and not to wait until v.6).
100% protection… that would be something I will believe in again. 
Egeman post shows how serious COMODO is for a Company and how they really work hard for the protection of end-users:

BUT, still COMODO has something to learn, as any individual on this planet.
COMODO needs to know that we (end-users/forum users, etc) are in the battle field and we can detect when somethings its wrong with a protection product such as CIS.
Lab work and field work compliment each other. So you gotta listen to us COMODO, because we want you to succeed. If you succeed, we also succeed getting excellent products for defense. 
I would definitely recommend you, COMODO, to go over the considerable numbered of posts that many well known users, with excellent reputation in the forum (not me included), that have being posting about the bypasses of malware and how to develop Defense+ better.
That way, we would have done our job, helping on creating a better product.
And COMODO will do its job and provide us for a better product. Its a circle of “trust”.
You are the closest company, in the whole world, to reach the 100% malware blocking.
