Hi! Yesterday I tried to install Kaspersky Antivirus and guess what … this program ordered me to remove Comodo Firewall because it is not compatible !!! Is this issue known to anyone and is there any solution to this problem ? Strange enough it doesn’t occur when I installed AOL Antivirusshield which is a slimmed down product of Kaspersky antivirus! (:SAD)

I had no issues with AVS except the well-known DLL Injection detection lags.

Did you install the lastest version ?

Running latest no problems, very stable.

Likewise, no problems here running the latest versons of both KAV and CPF.
Was it the Kaspersky antivirus version or the internet security suite that you tried to install ? :THNK

No it was KAV 6 … maybe i should install first KAV and afterwards reinstall comodo firewall ???

I don’t have a specific answer for you, although obviously other users have KAV and CFP. However, if you install KAV and then CFP, you will need to disable/turn off KAV before trying to install CFP, or it will very likely interfere with the installation and cause CFP not to function properly.

I would consider the other order to be more appropriate; CFP, then KAV, but that’s just me.


:-\ ohoh I did in the other way : I first uninstalled CFP and then installed KAV and than re-installed CFP again … It works but … how can i be sure that CFP does its job well ??? HELP !!!

There are tons of sites to check firewall security. Off the top of my head there is www.grc.com and www.pcflank.com . There is even a link on your CFP window that says something like “Test to see if your computer is secure.”

If KAV interfered in CFP’s installation, you’ll probably notice errors/problems with CFP, that it doesn’t work the way it should. Little things, most likely (not like a system crash, necessarily); monitors will be turned off, changes won’t update, etc. It is not likely to be something that you wouldn’t notice; in other words, there will be clues that something is wrong…

Regarding online test sites like GRC (or any other), be aware that if you are behind a router, the site is testing the router, not your computer. Also be aware that those sites are testing for port-controlling applications that will drop the packet they send to scan the port. This is what results in the “stealth” rating, rather than just “closed.”

A closed port (without packet-dropping) will give a reply of something like “Port Unreachable,” where a closed port (with packet-dropping) will give no reply. To the hacker, they both mean essentially the same thing - there’s a computer there, and the port is closed. A computer with open ports is an easier target… :wink:

The time to be concerned is if your ports are open. But be aware, if you run the test with an application like utorrent open, the specified port will be open; close these types of applications when testing. A better test (more reliable results) is to use a resident (rather than online) scanner, such as SuperScan by Foundstone, to test for open ports.


Well, CFP v3 is coming…

Its totally expected that people who will get affected from this will start positioning themselves agressively against this killer called CFP v3!

CFP V3 will change the security industry upside down, literally! Detection will no longer be your first line of defense… Prevention will be! Detection will become a secondary layer. This will cause a huge shift in the security market.

If your AV provider is not writing their software to be compatible with one of the most popular Firewalls out there then you have to seriously question your choice of your AV provider! We are lucky that there are many great AV products like NOD32, Avast, AVG, Symantec, McAfee etc.

There are many very good AV solutions out there for us all :wink:

There is only one CFP :wink:


Yeah. Desktop users will not need to pay for a basic set of security software again.

Hmmm, as for compatible AV’s we’ll all soon be using CAVS won’t we Melih ? (:WIN)


yeah sure: but I won’t use the AV until they solve the infamous HAL.ddl issue!

Sure. our AV is still beta. Until we release, you can use NOD32, AVAST or AVG. According to the feedback from our users, CPF + NOD32 is the best combo from performance and security point of view.

I thought nod32 was freeware - but i can’t seem to find that ver anymore. It’s all purchase subscrition based now. :-\

I just installed KAV 6 today since my BitDefender license is expiring, so far it hasn’t caused any problems with CFP. Hopefully it stays this way.
