Chrome Version 45 Update clashes with CIS
« Reply #30 on: September 03, 2015, 08:23:39 PM »
I had a problem with the Update to Chrome and Chrome not starting after the update. It turned out the new Chrome was clashing with Comodo Internet Security.  I fixed it like this

Add Chrome executables or whole Google Chrome -folder (e.g. C:\Program Files (x86)\Google\Chrome) into HIPS settings Detect shellcode injections exclusions. Steps to do this with current version goes

-> Open Advanced Settings
-> Security Settings
-> Defense+
-> HIPS
-> HIPS Settings: Detect shellcode injections [Exclusions] (lowest option)
-> Use 2nd mouse button to add: Files, File groups, Folders, Running processes

Which I got from this post from ngrpapu

Note: If you are on a 64-bit operating system, you can install Chrome 64-bit from https://www.google.com/chrome/browser/desktop/index.html?platform=win64 - I am able to run this successfully with Comodo 8.2.0.4674.

Issue re-appeared with Chrome 45.0.2454.85 and Comodo 8.2.0.4674 regarding guard32.dll/64.dll, same solution still working.

Add Chrome executables or whole Google -folder (e.g. C:\Program Files (x86)\Google) into HIPS settings exclusions. Steps to do this with current version goes

-> Open Advanced Settings
-> Security Settings
-> Defense+
-> HIPS
-> HIPS Settings: Detect shellcode injections [Exclusions] (lowest option)
-> Use 2nd mouse button to add: Files, File groups, Folders, Running processes


Thank you. Really. I am already have been upset about this whole thing with chrome, and finally found a solution. I even registered here to write a this message. Thanks!  :-TU

A workaround of sorts is doing the rounds - ad an extra dot between filename and extension in chrome, i.e. chrome..exe not chrome.exe - yes, it works. I am logged in here via chrome45, and I did have the above issue until I added the extra dot to the filename. Try it and see. BTW, a definitive fix should be earlier than Monday if possible, I am getting many calls about this from my customers, it is not a good look.

Renaming guard32.dll will compromise the security CIS can give you. You should rather go into advanced settings > Security Settings > Defense+ > HIPS > HIPS Settings > Enable "Detect shellcode injections" and click "Exclusions" next to it and in that window right-click in the list and click "Add > Files" then browser to the chrome executable and add it then click OK on all windows.

Thanks for your tips.  :)

This option is not documented and is not accessible to the common user. For sure until yesterday everything worked properly. Including Chrome.

The change to this security setting is certainly useful, but I think it should automatically exclude known and common programs like Chrome

Hi kRel,
The workaround generally isn't required, but the recent Chrome update unfortunately conflicted with CIS causing this bug to occur.
Please note: It has been acknowledged by Comodo.

Thanks.
Hello everybody,

We would like to inform  our users who had crash after they update their Chrome 44 to 45 ( related bug report is here https://forums.comodo.com/bug-reports-cis/guard32dll-kills-chrome-45-t112785.0.html;msg817958#msg817958); you will receive an update on Monday as we are now working on the fix and it will be released on Monday.

In the meantime, here is the temporary fix for you to apply:

https://help.comodo.com/topic-72-1-623-7731-HIPS-Settings.html#detect_shellcode_injections

Try adding Chrome to the Exclusions of Detect Shellcode Injections.Add the exclusion when chrome is not running, it will work after you add the exclusion and detect shellcode injections must be enabled for the exclusions to take affect.


For your kind attention please,

Best Regards
Buket

Hi and welcome The Fixer,
I am sure Comodo will make the fix available as soon as it is ready.
Note: Bug fixes need to be tested to be sure fixing one issue doesn't create another. :)

Thanks.

Firewall 8.2.0.4674 database 183 also kills chome on Windows7 & Vista, but the problem disappears when the Google folder in Program Files (x86) is excluded via:

Tasks>Advanced Tasks>Open Advanced Settings>Security Settings>Defense +>Hips>Hips Settings>Detect shellcode injections Exclusions

Hi and welcome Potager73,
Be sure to enable 'detect shellcode injections' found under Defense+ for the exclusions to take affect.

Kind regards.

You are going too far down the tree ... add the folder C:\Program Files (x86)\Google\Chrome to the exceptions
