Hello Everyone ! :slight_smile:

Here we are happy to announce that the COMODO Internet Security/Antivirus/Firewall fixes build is released ! Main focus of the release is to address a few security vulnerabilities that were recently reported by the Google Project Zero team.

PS: We’re very close to release our new major version of CIS which will include a number of new features and a brand new design, we will be updating you on this case accordingly !!

Thank you, great :-TU

Congratulations with and thank you for the new release. :-TU

Running the program updater but it runs an error at 10.3% when downloading the updates. Edit: it is fixed now and it downloaded successfully.

Thanks to the bug reporters, and thanks for fixes to Comodo devs :-TU It is sad to know tha we were vulnerable with these… but thanks god, now all covered :wink: Keep up working on CIS v9 8)

Thanks :-TU

Today is a great day, isnt it? :stuck_out_tongue:

Great to see these kind of bugs getting adressed… Keep them coming COMODO and keep devs around the globe as near as possible. Alltogheter for better security, for safe web surfing, for greatness!!! COMODO for life!!!

/Merchandising off :3

Cant read it. Please post print?

“Comodo antivirus forwards emulated Win32 API calls to the real API during scans.”

What does it mean? Is it a good thing?

Beautiful!!! Thanks for the tracker. So COMODO did solve the issues reported by him. Nice to see it. lets hope this behavior keep perpetuating for now on, by talking to other devs and working with them to solve things.

We have addressed all those bugs in this update guys. As you can read in the history in the bug report link, we worked with Tavis to make sure we understand the issues carefully.

Thanks Comodo. :-TU

I saw it. this is great egemen!!!

Do you know if some of these updates applies to ccav too?

Wondering what the “•New Home Page and Quick Search mechanism” means. Is that about those who choose to let it set their browser home page or actually about the “home page” of the product interface?

great work everyone!

What have you called “fixed”?
Even guests are still able to modify important Comodo’s files!
The simplest path to break CIS (even protected by password!) is the command:

%COMSPEC% /c for /R "%PROGRAMDATA%\Comodo" %p in (*) do copy %COMSPEC% "%p" /y

And what are you going to do with the weak hash?

No they do not apply to CCAV. CCAV uses different modules.
