Thank you for all your support, we are determined to make CCAV a better product with every new release.


Great job, umesh. :slight_smile:

Great!!!.. Thanks.

Thanks for the update:)

A user on malwaretips “Evjl’s Rain” tested CCAV against ransomware. CCAV blocked everything BUT petya bypassed CCAV.

Here is the thread, read post 18

Is by-pass here meant by shuting down the VM?
If petya didn’t encrypted any files I wouldn’t call it a by-pass (but still it would be nice if sandboxed apps couldn’t shut down your PC).
Actually, here is a video test of it: Comodo Cloud AV - Autosandbox only - petya bypassed - YouTube

Its a by-pass…at the end of the video he showed & mentioned “petya successfully encrypted the MBR & system is not bootable”.

Yes, thus I’ve edited my post and posted a video. :a0

Hi Yash Khan,
Thanks for bringing attention, team is checking. We will get back soon.


H All,
This has been identified and under QA.

We will have a release by this week-end and it will have this fix also.

This bug got into CCAV in v403 released on Dec 21, 2016 else all previous versions protected against Petya.


Hi guys, I see the recognizerCryptolocker.dll version in Viruscope is only in CCAV latest, but at a much higher number in CFW for example, not the same?


Hi woodrow,
We have a recognizer version under QA in CCAV, we hope to have it out with next to next release.


hope it will be strong!!! :slight_smile: :slight_smile: :slight_smile:
