Comodo Internet Security v10.0.2.6396 Released

Hi All,
We are pleased to announce release of Comodo Internet Security v10.0.2.6396.

We highly appreciate all users, who participated and provided valuable feedback in last RC and BETA releases.

Here is the change list:

AV component optional in offline installer:

There was a request from users, who wanted to have offline installer for Firewall and didn’t want to install Antivirus component together.
Now during installation, user can select both or either of the two. Please check enclosed AV_Optional_In_Offline_Installer.png.

Crash Reporting:

In case any CIS component crashes and if user is not participating in sharing application usage and statistics (Option: General Settings–>Logging → Send anoymous…),
he will see example alert (please see CrashReporting_Alert.png) requesting user to allow to upload crash dump to Comodo server for further analysis. This will enable us to find out crashes in the wild and every release down the road, will include fixes of the same. We introduced this feature in CCAV and has greatly helped.

Automatic Update Download and Installation in Critical Situations:

Considering Windows 10 is evolving very fast, we have seen in recent past that there had been incompatibilities between Comodo and Windows 10.
Even after releasing CIS updates, some of users do not read releases notes and do not update to latest program version, however Windows may update automatically. This creates a situation where even though we offered update, user declined the update and could run into difficulty.
In order to avoid these situations, we have decided to introduce an option “Automatically install program updates…” under “Settings → General Settings → Updates” section. Please have a look at enclosed AutoInstallUpdates.png. It will be selected by default and if that is selected, updates will be automatically installed and if applicable, user will be requested to re-start system on his convenience. We will use this only in critical situations.

Right click scan to use Cloud (New ‘Manual Scan’ Profile):

At the moment, right click scan uses settings from “Full Scan” profile, where cloud lookup is disabled by default for performance reasons.
When user right clicks and scans, user really expects file to be thoroughly scanned. So we are introducing “Manual Scan” as a new scan profile with cloud lookup enabled by default.
This new profile “Manual Scan” will be used whenever user right clicks and scans a file or folder. Please check enclosed New_Manual_Scan_Profile.png

Trusted Root Certificate Scan:

In order to protect against Man in the Middle (MitM) attacks, when you run Rating Scan, it will also scan for presence of suspicious root certificates in system.

Optional online access for files on Network:

In order to improve performance of browsing network files, we have introduced a new flag under “Settings–>Antivirus–>Realtime Scan” as “Enable realtime scanning of files on network”.
This allows to control if files on network should be scanned when you browse network folder or copy files network to network i.e. one folder on network to other folder on network. This is de-selected by default for performance reasons. If you want, you can enable and files on network will be scanned upon access just like local files.
In any case if you copy network file to local system, files will be scanned. So this feature is only for files on network.
Additionally, when older version update to this newer version, this flag will remain selected, going forward for new installations, it will be de-selected by default.

Compliant to Cloud Files Feature:

This version is fully compliant with latest Cloud Files Feature introduced in Windows 10 RS3 release.

Improved Auto-Sandbox notification:

Now when an application is auto-sandboxed, notification has an option not to isolate again. Please check enclosed Improved_Auto_Sandbox_Notification.png.

Improved System re-start reminder alert:

Earlier, when alert was shown, it used to steal focus and inadvertently user could end up re-starting system while in the middle of other work.
Now reminder dialog will be shown on top but without being as active window and even if active for some reasons, default active button will be “Postpone”.

Improved “Unblock Applications” interface:

Now you have ability to:

  • Unblock a blocked application from respective blocked component or from all components.
  • You have a Purge button as well to clean up non-existent files related entries.
    Please check enclosed Improved_Unblock_Applications_Interface.png

Website Filtering:

- Cloud based threat database: Till last production version we used to have localized malicious url database; This release onwards, we have this database cloud based with support of local heuristic database that’s version number you will see in About box. This database is updated every time AV database is updated.
- Additional malware categories: If you go to “Settings–>Website Filtering” section and try to add a category in a rule, you will see additional categories, which are filled up on the fly and will allow us to add more categories in future without client changes.
- Default behavior for blocked sites as “Ask”: If you see default “Blocked Sites” rule, earlier websites in defined categories were set to “Blocked” as default Restriction. Now you can see default value as “Ask”. This means now if website is blocked, user will be having option to continue, if he wishes so. Please see enclosed Blocked_By_WebFiltering.png as example blocked page .

Other Changes:
“Scan Exclusions” section has been moved from “Antivirus” section to under “Advanced Protection” and it also has a new tab for “Excluded Certificate Authorities” as may have been added to exception during certificate scan.

“Detect shellcode injections Exclusions” present under “Settings → Advanced Protection → Miscellaneous” has been renamed to “Disable shellcode injection detection for these applications” to reflect exactly how it is implemented.


  • WDSC status bug as reported here has been fixed.
  • If you update to RS3, firewall may not be fully functional and required system re-start as a fix. Issue reported here.

Changes in Secure Shopping (CSS):
This version installs new version of CSS as v1.3.427860.115 with following changes in it:

When CIS is installed, you will see Comodo Secure Shopping shortcut on Desktop. We want to highlight this great feature as user can use it as starting point for secure browsing.

When you launch Secure Shopping, you will see a welcome window. Please see enclosed SecureShoppingWelcomeWindow.png
This is to highlight benefits of Secure Shopping, with check box not to show again selected.

In standalone mode i.e. when Comodo Internet Security is not installed, you will see following changes:
We are avoiding alert model and now if you define a website in Setting, and if website is browsed in supported browser, it will be opened in Secure Shopping environment. Please have a look at enclosed CSS_Setting.png

We are going to have continuous CIS releases down the road. Your feedback is very much needed.
Please stay tuned.

Mod edit: Added CSS_settings.png

Hi umesh,

Thanks for the new release :-TU

With the website filtering now evolving, is this integrated with Dome Shield or completely separate ?

If it is separate, are the two going to become one later or stay separate ?

:-TU :-TU :-TU

Released prematurely ;D

Audio service still showing as “not running” on Win10x64. Have to manually restart the service after every OS restart. Also, check the screenshot. CIS is missing from security center. Classic shell still changes color. At least radeonsettings.exe is causing no troubles anymore :-TU

Do I need to enable DNS Comodo to block malicious sites from the database?

No. They are independent.


Thanks for this released. I stopped to use CIS as is not working well it made my PC frozen and slow.
Install only Comodo Firewall seems works better.

CIS and Firewall isolate unknown program but CIS do not ask me always… the Firewall separated from CIS seems work better and ask before isolate a program.
Why the Secure Shoping cannot be present also in the setup of the Firewall only?

I have Comodo Firewall installed right now, for have also Secure Shopping I AM forced to uninstall and install CIS?
Maybe in the future you can consider to add Secure Shopping also to onlt Firewall setup / installation.

I guess SS requires the AV component.

No 23 is not see:;msg867850#msg867850

Oh, ok then!

Comodo Firewall not detected in WDSC (while it is on control panel)

Hi peopleinside,

Did you try this version? if yes, we would like to troubleshoot.

We will be making Secure Shopping independent product, so it can be downloaded and installed separately.
In the mean time you can download using following link and install:

We will consider offering like we offer browser.


Can you please share Windows OS details?
Build and version in case of windows 10.

You have to consider that I use Comodo since a life and always had this frozen issue. Is a very old issue.
What happen? I install CIS and after maybe 20 days PC is frozen so I need to reboot. I discover my PC was frozen sometime from CIS because two day ago I opened CIS and was very slow in every command I use in the panel: standard view, advanced view, etc.

Also create a program Crash because program was sandboxed without asking to me.
This caused a big issue as my PC get completely frozen again, I removed that program and I had to re download 18 GB from a slow Italy Internet 7 MB

Only CIS give to me this issue so now I use 360 Total Security and as I love Comodo and think is very secure I installed the Firewall of Comodo.
The Firewall of Comodo for now seems work well and the same program that was blocked without asking me on CIS con Comodo Firewall only has been approved by a notification showed to me.

My PC is more faster now with 360 Total Security with setting as Security (all antivirus engine active) and Comodo Firewall active.
Seems Comodo Internet Security has not only for me performance issue:

see the performance score here:

seems to be really true.

Thanks for you help.

That is how it is supposed to be, but if you click on virus & threat protection or firewall & network protection, you will see comodo listed.

Windows 10 Home 1703 build 15063.674.
I’m going to upgrade to 1709 and I’ll let you know about WDSC

Not for me, no sign of CFW under firewall & network protection

Ciao Jon,
you see this message because your Windows Firewall are deactivated.

I see from your first screenshot where in the Italian language Windows alert that Windows Firewall are not active. Please try to follow the button to use suggested settings on Windows Firewall, the issue should be resolved. Activate Windows Firewall.

Hi umesh

Did you try this version? if yes, we would like to troubleshoot.
If I decide to test CIS again how I can help you to troubleshoot the slow and frozen PC or CIS if you do not have remote access to my PC?
