So which would you choose, avast free or kaspersky free, based on level of protection & performance?
Avast free vs Kaspersky free

KART has the KSN based File AV while Kaspersky Free also sports KSN. May or may not be a considerable issue.

i don't see the problem some files being checked on KSN twice if there are no performance issues.

Might not be. However, things aren't technically as simple as they look by definition of their work right?
And the File AV of both will have the task of dealing with any identified malware (via cloud) and both may pounce on it.
this point is i think why some people think there might be some incompatibilities
if both KART and KFA find a suspicious/malware file and both go to remove/quarantine it, only 1 is going to actually get it. Which one? Will the one who missed it cause a problem? Or will it notice that the file was already taken care of, so then just ignore it and keep on going? Or will both apps notice each other are trying to deal with the malware, so will both assume the other app will take care of it? so then both ignore it? etc etc
there can be many scenarios that could potentially cause problems, we will not know until we test with both installed on same system or if Kaspersky themselves tell us its ok to use both
these are the settings available from KART version 2.0.0.176
as you can see, they are very lacking in options
lol

Kas Free has to demonstrate that it is not just the well-known name. What? Kas Free has less features than paid versions? yes, and? It has to offer good protection, altought it's a Free soft., we need to test it to compare it with other free solutions, because, altought there is a paid version than probably offers better protection, for people who look for a free solution do not care that at all.

KAV and KAF are almost identical, what's there to test? same sigs, same KSN, same AV modules that are available in both of them...
you sounded like Kaspersky just released some brand new product that needs to be tested cause who knows how it performs, except in this case everyone knows, like KAV.

You've covered the many cases that may question many users.
It's not just about the two AVs and what each one will do...the OS has a big involvement here.
Both will be working on a kernel level. On detection, each will have a long list of operations to register for in the system (for things like resource control) for every individual action they perform from intercepting to dealing with locks (deadlock in certain conditions?) to cleaning or disinfecting the malware.
The dashing can result in as small of a trouble as a system slowdown to any big conflict leading to crashing of either or both programs.
You're right. Testing the duo with varied malware can give us some insight into the compatibility.
you can always use firewall to block KSN
back to topic
for now I would recommend KAF only with other security soft (comodo, VoodooShield, ...), not as standalone

Reading @Parsh 's message above, saying that Kas free does not have BB, seems to me that Kas free will not have the same results as KAV..

i actually feel retarded for forgetting KAV having System watcher/application control.
i'm sorry, forget it.

Hi, I have on my PC (Windows 7OS) Avast free + Comodo Firewall configured in this way:
Comodo firewall: Enabled Firewall + Auto Contaiment.... Disabled HIPS + Web Filtering + VirusScope
Avast Free AV: Enabled "File System SHield" + Behavior Shield + Web Shield....All the other features are disabled
Do you think that using Kaspersky free instead Avast could be better or not?
Better means: performances + virus detection + less conflicts with Comodo firewall

Are you using CS settings for Comodo FW? If not and since you're into auto-sandboxing, first switch to 'Proactive Configuration' in it and then make any other changes in CFW, since switching to Proactive will reset most of the settings manually selected.
If you're using CS settings, you might not need a Behavior Blocker from another AV (though I recommend enabling Viruscope in CFW) and Kaspersky Free will be great together.
The CS settings have aggressive way of handling the unknowns. You will have strict restrictions on elevation of unknown files and block outbound connections of sandboxed programs. And added folder protection...
However, there are slick chances that the File Lookup will allow a harmful file to run un-sandboxed (the file might have been set as trusted by a Comodo analyst etc.) or a malware uses a certificate of any vendor that's trusted by Comodo (this won't be a big problem if you totally trim down the Trusted Vendors List to a few well known ones in CFW). In such cases of vulnerability, having a complementary AV with a good BB will be useful in case the signatures of the complementary AV do not intercept that piece of malware with stolen certificate. Here, Avast is the forefront runner.
Another point is that better the signatures of the complementary AV, less of sandboxing work CFW will have to do. Here, Kaspersky Free leads.
As you can see different benefits of Avast and K Free, now you'll have to decide upon these points. I'll suggest you to keep Avast Free if it works fine for you. K Free apparently has no conflicts too, with CFW. Just ignore the incompatibility warning that you get while installing K Free on top of CFW in case you decide to switch.
So, your suggestion is to change some settings in my Comodo + Avast AV respect the actual?
I should change the settings in this way:
Comodo firewall: Enabled Firewall + Auto Contaiment + VirusScope + Change from "Firewall Security" to "Proactive Security".... Disabled HIPS + Web Filtering
Avast Free AV: Enabled "File System Shield" + Web Shield....Disabling "Behavior Shield" and all the other features

Yes, except that you can keep Behavior Shield enabled for the rare case that some malicious program is missed by CFW auto-containment in some ways I described above.
For further strengthening, you can refer to CruelSister's CFW settings in the video link I shared in my previous post. Select which additional settings/restrictions you would like to add from that video (like restricting elevation of unknown files, disabling "do not virtualize access to shared folders" etc.)
HIPS is an option, you don't need it here unless you're paranoid about controlling everything happening in your system. There are different modes available as described here.
This is the reason I always keep Behaviour Shield turned on with CF. While it's incredibly rare, if you come across malware that's trusted by Comodo or you unblock an application you believe to be safe that is actually malicious (this is assuming the AV doesn't have a signature for the malware) the behavioural blocking can save you a real headache. Especially if it's something quiet like a RAT that's recording your keystrokes/mic audio or snapping screenshots/images through your webcam.
Something like ransomware is trickier as unknown samples usually end up encrypting at least some files before the behavioural blocking kicks in, but if you have backups then it's A-OK.
