New Version 12.3.3.8152 Available for Comodo Internet Security 2025

Hey everyone,

Good news! We’ve just rolled out version 12.3.3.8152 of Comodo Internet Security 2025, which resolves the recent certificate issue. You can now download this updated version directly and enjoy the latest features and full functionality:

First and foremost, your protection was never compromised – all core security layers continued to operate as expected for existing installations. The main impact was that the CIS 2025 installer was blocked due to the invalid certificate, meaning new installations weren’t possible. Additionally, some functionalities – like activating the warranty and downloading extra components (e.g., Comodo Cleaning Essentials (CCE) and KillSwitch) – weren’t fully accessible.

If you already have Comodo Internet Security installed, you can update to the latest version by simply downloading the installer and running it to install the new version without uninstalling the existing version. We’re still working on enabling the direct upgrade feature, but this method will get you up-to-date without any issues.

Thanks for sticking with us, and we’ll keep you posted on our progress!

Best,
The Comodo Team

Hi ilgaz,

Thank you for your work in fixing the certification issue. What’s the progress on this bypass issue? As far as I know, it has not been fixed in this latest version.

From what I understand in the other topics, only the revoked certificate was corrected.
But not the baypass.
How long will it take to correct this?

Thanks!

That’s great, but now it’s time to put this version on the website. I know it’s extremely complicated to change out a file on a web server, but it should be done. It should take minutes, not hours or days.

Hi,

If you’d like to work on website too, contact me because in France, the 1st site referenced is this one and the French translation is just ugly

These updates are still not delivered automatically right?

Why won’t the Downloads folder be added to HIPS Protected Objects by default?

Алекс? привет! А накой она там нужна. Кроме папки Комодо в исключениях изначально нет ничего. Что в общем то не мешает добавить ее вручную, с осознание всех рисков этого действия.

I just upgraded to this version from version 12.3.3.8140 (firewall only) by “simply downloading the installer and running it to install the new version without uninstalling the existing version”.

Here are my intial findings:

  • Installer does not detect the installed products (firewall only in my case) and tries to install the full product (so also antivirus). You have to explicitely uncheck the firewall in options.
  • After upgrading, the configuration that was active before upgrading is not loaded. Instead the default configuration is loaded. Luckily, the old configurations are kept as separate versions, that can easily be activated.
  • Because the default configration was loaded, I was asked to either ‘activate the product with a license key’ or ‘upgrade’. The upgrade option takes you to the page of CAV 2022! Luckily, you can simply close this window.

So, while I’m glad Comodo is still alive, the user experience of the upgrade process could use some improvements. And the ‘post installation’ welcome screen is very confusing (activate or upgrade).

Correct, just like with everything else they are so slow to provide updates through the program updater.

I’ve given up hope that they will ever put any serious effort into truly improving things for CIS. We get whatever time they have left after they work on more important things like Xcitium. I’m just glad we finally got an installable version again.

Привет! Он самый с Comss))) Я в ручную и добавляю. Я не про исключения, а про защищенные объекты в HIPS.

I have a problem:

I don’t think the installation was successful. However, the diagnostics say that everything is fine.

If you look at this screenshot, it seems to me that some executables are missing, don’t you think?

Killswitch, for example, isn’t here (?)

But I’m surprised the Diag didn’t notice…

What should I think?

I can’t find out much more, because Comodo CIS Pro is blocked by my licence not being recognised. (more)

I’ve installed it three times and it’s the same thing.

Plus an update, same thing.

Each time with a clean uninstall.

You have to install Killswitch after you install CIS/CF via the UI
