that is irrelevant.
Has online armor a problem with web shield or not?
Any conclusive tests done. 8)

I use Private Firewall and have encountered no problems. Of course I made the proper rules/exclusions in both avast and PF.  :)

The testing is done by the numerus members of this forum and many others who actualy use OA and avast together with no problems.

Sorry for resurrecting this old'ish thread but what is wrong with using Commodo?

I have used that firewall for ages with no problems (that I know of) and periodically test it via the grc site https://www.grc.com/x/ne.dll?bh0bkyd2 (https://www.grc.com/x/ne.dll?bh0bkyd2).

As far as I'm aware it doesn't conflict with avast (may be wrong there). I have added avast as trusted path in commodo but not the other way round.

I'd like to hear some opinions

Much simplified answer.

Depends on what OS you are using, if win7, then the comodo firewall can't differentiate between what process is being redirected through the web shield proxy as it doesn't have support for the latest windows redirect API.

So if you have rules that try to block an application from connecting to the internet, if that connection is using http protocol it will be redirected through the web shield proxy (which is allowed in comodo) bypassing the rule to block it.

Ah, that's interesting.

Must get my behind over to the Commodo forum to see if there are any rumours of fixing that  :(

May I ask what your recommendation for a firewall are?

Just read your signature ... I assume its outpost

Thanks for the help

By all accounts the comodo forum has had a deafening silence if they are going to fix it and if so when. I believe they would rather you used their suite.

Mine is the Pro version, not free, but I have been using Outpost Firewall in many versions from Outpost 1.0 free. I bought a lifetime license for Outpost Firewall Pro many years ago at version 3.0 (a bargain at the time for the cost of a single years license). I have since bought another lifetime license for my other system.

But there are many free firewalls, even a free 7.0 version of Outpost Suite, a custom install is required not to install the antivirus module.

I used OA++ for a couple of years with absolutely no problem with Avast.
The Emisoft forum is also pretty good for support.
Just found the firewall a bit too busy and didn't like the "Banking Mode". Didn't work properly!! :) 8)

Well, I was over at the Comodo forum, the first time even though I have used the thing for a long time.

You are right, a fix for the issue is unlikely soon.

I've got to make choices.  Its almost like loosing a good friend as both programmes have done their job great for me (as far as I know), save the odd glitch or two  :)

Its clearly not an issue that Avast needs to solve but it does pose a vulnerability which at the moment I am not clear how serious (or not) it is in the greater scheme.

I could, I guess, revert to avast 6 for the time being and be done with it, loosing some extra protection of the latest version.

Tricky, I like Comodo and I like Avast.

Its a bit like two stroppy children playing in a sandbox (!). Which one to remove ... ?

No contest, get rid of comodo, you didn't expect anything else did you ;D

Seriously comodo will have to fix this at some point as this is the new windows redirection API and will be exclusive in windows8 and depreciated in win7 although it still supports the old API, you could pick it back up later. As mentioned there are other firewalls that are compatible and I certainly wouldn't downgrade my AV protection for the sake of a firewall.

Avast 7 already has win8 compatibility and has for some time, looks like comodo have some distance to go yet on win8 compatibility.

As always, you make sense.

One question though is about something I don't quite understand; Is avast using heuristic scanning or is it based on known codes? - What are the pro's and con's of these?

Thanks

Avast uses a number of different methods, standard virus signature detection, Heuristics, behavioral, Emulation, Reputation (file known or widely distributed, etc.). The AutoSandbox being another tool in the box.

The idea of heuristics is to try and detect something suspicious by other methods rather than its known virus signature, that is a very simplistic explanation. It is trying to detect that which hasn't yet been detected conventionally by virus signature. So the word heuristics can actually mean many different things and if you read some companies interpretation of heuristics they differ to fit what they are doing.

Thank you for the replies.Im going to stick with my OA and avast combination as they seem to work just nicely together. 8)
