Comodo Firewall – On Again, Off Again

I have been working on computers for so long, that it is sometimes difficult to remember a time when I wasn’t doing some type of a build, repair or software install. I have also learned that when it comes to software, for some odd reason, there are usually some type of glitch that prevents ANY software from working correctly on a given machine. So knowing this in advance, when I experience a software issue, I don’t get very excited about it. So it was on Saturday morning when I fired up my machine.

My normal routine after boot is to check my email and then wonder over to the Lockergnome site to approve comments. This is where I first encountered a problem. The Lockergnome site would not come up. At first I thought it was the site itself, but after trying my wife’s system and also my gaming rig which both brought up the site just fine, I determined it was my system. Strange. All was well on Friday evening. But what the heck, stuff happens, so I did a routine maintenance, ran both virus and spyware checks just to be safe. All was well.

Back on the Internet to another try other sites. It was hit and miss. Some would not come up at all while others came up slowly. Since my other systems were working just fine, I knew that my cable modem and router were working OK, so I tried turning off my wireless on the lappy and did a hard wire connection. Same thing. Another browser, same thing. I also subscribe to the old school thinking, last program on, first program off.

Unfortunately the last program I put on was Comodo firewall. Off it went. Back on the Internet and all was well. Now, since I had reinstalled Comodo back on 7-18-07, I haven’t had a problem with it. Nothing all all. Zilch! I know, I know, I guess some will want me to trouble shoot and find out why it didn’t work. That’s not my job. There are too many other firewalls to use that are also are free. But I will say this. I like Comodo and I will give it another try when version 3.0 comes out. :-)

Comments welcome.

    I knew this day would come. But the real question is…how hard was it to remove? If they have improved the removal routine THAT would be great progress.

  • Ron Schenone

    Hi Marc,
    Removed without a problem. :-)

    I’ve been reading this and the various threads regarding Comodo, and I thought I’d throw in my two cents. I’ve been using CPF for a year and a half or so, and other than an initial problem with utorrent (easily remedied), I am pretty happy with this firewall. It’s a bit time-consuming at first, but it still passes more leak testing than the formerly wonderful zone alarm or sygate ever did. I use it with my extension-heavy Firefox install and (and occasionally Opera) without a problem.

    That being said, it is a resource hog – it two processes (cmdagent.exe and cpf.exe) consume about 25MB of memory at a minimum, and the lack of hotkeys is a pain. Only recommended for the paranoid or the geekalicious.

    Hello jahnbon,
    Thanks for sharing your experience with us.

    I had a problem with Comodo this morning. It blocked Firefox and I thought my internet was down. After unblocking Firefox all was well. On my system it uses less than 10 MB.

  • Eric Krouse

    Hello, I have had similar problems with CPF in the past, but what are you gonna do? I still like the program. Less problems with it than I have had with ZA or Kerio. The BEST I’ve used has been Tiny Firewall, but its not freeware so I haven’t used it beyond the evaluation, but would consider buying it.

    I’ve been using Comodo Firewall in various versions (betas, etc) for more than a year and a half. I’ve really had only one problem and that was with one particular laptop it would block the internet entirely. A removal and reinstallation fixed the problem. Other than that, it’s been an exceptionally good program. It is a fast, user-friendly install and requires little user input for configuration. Pop-ups give you clear info as to what is trying to access the internet and gives you options to allow or deny and to send the file to Comodo for evaluation. If you’re looking for a simple, effective free firewall, this is the one.

    Hello Oliver, Eric Krouse and Hunterx14,
    Thank you all for your comments.

    I appreciate all of you sharing your thoughts and experiences.

    I had the same problem on two machines.
    On/Off – I thought it was wireless interference in neighborhood.
    Uninstalled – later re-reinstalled COMODO it fixed the problem.
    But what a pain it was over many days finding the source.
    It is rated as a good product but thanks to sharing information
    I see that I’m not alone. I was unable at the time to try the
    direct wire connection. The other computer was my neighbors.
    Thanks for the ‘heads up’ all.

  • Ron Schenone

    Hi FCiso,
    Thanks for the info. and also for your comments.

  • Robert

    Why dont you guys just get a Mac and leave Window’s and all of it crap behind.

    I did and I cant tell you how much happier I am. Also I dont waste time looking for viruses, malware, adware or trouble shooting my system every time some goes wrong.

    Anyway just my 1 1/2 cents for what it’s worth and food for thought.

  • Ron Schenone

    Hi Robert,
    I believe that there are quite a few people who may just do that. I’m giving serious consideration about Linux. :-)
    Thanks for the comments,

    I have been using Comodo for a few weeks and thought it was pretty good, especially after I ran a Sygate Online Test
    Then I went to Shields Up
    and ran their test. There I found that only about 10% of my ports were ‘stealthed’ and the rest were closed. NOT GOOD!
    I enquired on Comodo’s Forum and was told that I must have an old version and I should get ver, exactly what I have. I have downloaded it twice, installed, un-installed twice and tested it several times, with the same result.
    I have used Outpost for the last couple of years and always had all ports stealthed. I changed to what appeared a great firewall, when I had a couple of quirky things occur with Outpost.
    I never expected to find that my PC is on view to the world, after all the glowing reports. Funny though, because I can hardly find a comment about stealthing and there is virtually no mention of stealthing in any documentation available from the Comodo site.
    So, what is the truth? Does Comodo hide your PC online or only when you have your PC powered OFF? If it can provided stealthing, then it should be a default setting and not require a degree to set it up.
    I do hope this can be overcome, because I bet that no one using Comodo has full stealth protection, they just don’t know it and it seems to me, it ain’t up for discussion.

    Hello Esra Trams,
    Your experience says volumes about waiting for version 3. :-)

    That worried me, as i checked with grisoft after installing a while ago.
    I have just revisited shieldsup and all service ports are stealthed.
    cfp same version as you.
    Have you resolved it yet?
