I lost my breath reading your post.

I hope you don’t mind, but I moved this out of the bug reporting section, as this was not related to any particular reported bug.

Also, I’d like to mention that from what I’ve seen most of the major security vulnerabilities have been fixed. There are still a few remaining, but I believe these should be fixed soon as well.

As for your screenshot about the leaktest results, please see this topic. The leaktest itself is not really meant to be used for the newest version of Comodo Firewall. Due to the way Comodo Firewall works unless you configure Defense+ a certain way the leaktest will erroneously show that your computer is vulnerable, whereas with real malware you are safe.

As for the connections you are seeing, I believe this is likely due to your connection with the Comodo cloud. I could be wrong, but I’m sure others will be able to comment more on the connections.

As for malware removal capabilities, please try using Comodo Cleaning Essentials, which is bundled with CIS.

Let me know if you have any other questions.


The traffic at ports 4447 and 4448 are for Comodo’s Cloud. There is no secret here. CIS uses cloud look up as a corner stone. That is public knowledge. Most security programs these days have a cloud component.

The Comodo Leak Test was made to test a HIPS firewall like v3.x back in the days. It will give false results on mixed sandbox/hips based solution like CIS in post v3 guises. To learn how to properly use CLT with post v3.x variants of CIS please follow Getting Accurate Leak Test Results in Leak Testing/Attacks/Vulnerability Research.
