Hello,
Just want ask if i can combine comodo firewall with avast internet security? thanks! 
No.
You can combine Comodo Firewall (and Defense+) with avast antivirus free/pro.
So if you combined comodo firewall and avast! free/pro, is the outcome would be as if you are only using Avast IS? or its better to use comodo firewall + Avast! free or Avast IS alone? thanks again!
I read this topic and I wanted to leave my opinion
From my personal experience, Comodo Firewall + Avast 5 free gives an excellent level of protection. (It has saved me quite a lot of times from getting infected with USB worms)
By the way, I have never tried AIS (since I don’t have either the money or a nearby reseller).
Cosmeglenn, due to Comodo sandbox and HIPS (Defense+), I think avast antivirus + Comodo Firewall + Defense+ assure you better protection than AIS.
Yeah, the combo of free is better than the paid imho.
@Tech
I don’t doubt that you’re right, but having tried avast free antivirus + Comodo Firewall + Defense+, AIS is easier.
To anyone,
what about malwarebytes + avast internet security? is it ok?
Generally, any suite is “easier” than a combo.
But, is it safer?
Look a most recent topic in the forum… http://forum.avast.com/index.php?topic=64494.msg545168#msg545168
Yeah, you can run MBAM on demand with AIS. Good combo for detection (have my doubts on protection).
So you prefere Avast Free with Comodo with Defense+ is better than Avast Internet security?
I’ve used the combo: Avast 5 Free and Comodo Firewall 5. It is NOT better than AIS.
_Yes, Comodo Firewall will pass all leak test’s you throw at it but, honestly, I don’t trust it. The firewall doesn’t have as strong inbound protection as Avast in my opinion, and, excuse me but, preventing things from infecting your system is FAR BETTER than preventing them to “leak” afterwards.

thanks mastertb! so for you it is better to have AIS alone? what about AIS + Malwarebytes?
Now im confuse what to use 
MBAM + AIS? good detection but not sure of protection ( as told by tech )
Comodo firewall + Avast free? good protection but what about detection?
What About MBAM + comodo firewall + avast! free ?
Please help? Im always using the net everytime im infront of my pc.
running AIS, core i3 540, 2gb ram, window 7 pro 32 bit
just go (or stick to) for AIS…after all you’re on Avast forums, and we’re not here to advertise the competition. Try AIS (trial version) if you don’t have a license yet, and if you’re not satisfied with it, post your issues, and if in the end these issues can’ be solved, if any, try something else, Comodo being just one alternative.
MBAM (free) on demand improves detection.
To improve protection you need MBAM (paid) or CIS (free).
Very good.

i have already installed comodo firewall + avast! free + MBAM. The action center said "multiple antispyware programs report that they are turned on and up to date, NOTE: Running two or more antispyware programs at the same time can cause your computer to slowly ".
should i just ignore this?
Which programs are listed there?
Avast antivirus, comodo defense+ and windows defender.
Well… Comodo Defense+ is a HIPS and not an antispyware tool.
I won’t worry about that. Both programs are compatible.
Thanks a lot Tech!
