Hello,
From beginning, I want to emphasize that no one could better as Melih explain the
direction in which computers protection will go. I think there is no product in
this world to protect against Zero Day attacks, but the important thing is the
direction which the Internet Security Products is going to reach this ideal and
I think Comodo Internet Security is one of them (actually am sure now

).
What I say is of my own experiences after an extensive testing of many products
based on classic AV (based on detection). I can say that in the last 6-7 years
from all products tested by me (bitdefender, avast, avira, zone alarms, pctools,
avg, mcafee, symantec and kaspersky) no one could provide me "peace", what to
say about a kind of "warranty" of protection against new malwares appeared on
the market. For conventional products based on detection, what matters is or
a good basis with signatures (which could mean many infected computers),
or a good infrastructure to detect new malwares so that the product be best
on the market. But I think this is not enough to present day. The only product
that impressed me was Kaspersky, but unfortunately not convinced me. Therefore,
in the past three years I started using Comodo as impressed by defense+ module
(HIPS technology) and I realized that this is the right direction of computer
protection, but something was missing. The missing thing was completed now
with whitelist and the sandbox. This was the first thing that made me believe
I found the product wich I'm looking for.
Most products have these modules into their component: Detection / Cleaning
and Prevention. The most classic AV are based on Detections and Cleaning but
but not so much on Prevention. What they offer in terms of prevention do
not cover the full range of new malwares on the market. The second thing
wich convinced me that I found the product wich I'm looking for is how
the three modules are used:
1. Prevention
2. Detection
3. Cleaning
I am aware that this technology is under development, but what matters is
that I found the product which can lead in the Future of Computer Security.
I can not conclude without trying to answer the question: Is Comodo Internet
Security the way to Protection against Zero Day Attacks? I think YES and if
not yet, I'm sure is the right direction!
Keep up the good work Comodo!

Best Regards,
Ovidiu
