Proactive Defense i.e. Defense+ now includes a built-in sandbox which combines file system/registry virtualization and least-privileged user account principle in order to combat with unknown malware.

IMPROVED! Significantly fewer number of popup alerts
Defense+, with the help of new sandboxing technologies, has a more powerful default security policy while having significantly fewer number of alerts compared to previous versions.
Also in this version, Defense+ and Firewall, by default, do not create automatic rules for already known safe applications.
IMPROVED! Popup alerts layout
The new popup alerts now include additional options which allow the users to take COMODO Time Machine snapshots or set Windows system restore points, submit suspicious files for immediate analysis.
IMPROVED! Antivirus Engine
Antivirus engine is improved for better detection and cleaning. The new engine now has disinfection support for the infected files.
A new command line virus scanner (cavscan.exe) has been introduced in order to address the need for scanning the computers in windows safe mode or scanning files transferred from MSN etc.

Frequently Asked Questions

A1 - No. The installer will download the appropriate setup for you and install.

Q2 - I am a CIS 3.x User. Will I get the updates?

A4 - You should uninstall the BETA version and use this new version. However, although not recommended, you can use automatic updater to update to this version from the BETA versions.


1st post here :slight_smile:

good job

Thanks :slight_smile:

Thank You, COMODO! Starting download.:))

After installing only the Firewall part of CIS 4 my download manager Net Transport v1.87.258 crashes at program startup. How can this problem be solved?

Defense+ is disabled and my OS is WinXP Pro SP3.

EDIT: I’ve uninstalled CIS 4 and reinstalled CIS 3. I’ll try the next release of CIS 4 when it comes available, to see if the problem is fixed.

What a great birthday present. Thanks!

Not to put comodo down or anything but how much of those bug reports in the v4 RC sticky got fixed? I am going to wait at least 2 weeks before I put them on my windows 7 and xp laptops and my parents computer.

:‘( :’( :‘( :’( :‘( :’( :‘( :’( :‘( :’( :‘( :’( :‘( :’(

i am liking the sandbox notification. Simple and nice.

Is this the Final Version? Just asking and I will try this one out to see how it works.

Probably FP’s :slight_smile:

The wait is over… ;D Installing as we speak. Great work guys! :-TU I’ll be back to complain a bit later. :wink:

Alright Egemen and the rest of the team, now when can we expect v4.1 :stuck_out_tongue: ;D

Yeah really…you guys take forever… ;D

you guys said there will be shortcut keys for hips disable / enable in version 4 , and there is none :cry:

can you expend on what u mean a bit more?


One more thing, now that v4 is here I wonder which CIS version is going to be tested at matousec, latest v3 series or the newest v4? If it is v4, I wonder how the results will be interpreted, will they penalize or criticize comodo for “confusing the tests”. Or will they praise comodo and say something like “comodo uses virtualization/sandbox technology to prevent these tests and malware from modifying the actual file system and registry which protects the user”. Part of me wants them to test v3 just to see how well it would rate with the new tests compared to other products. But I would also like to see the power of v4 sandboxing/virtualization capabilities.

Congratulations with the new release…(:CLP) :BNC (:NRD)

Will install it soon after this reply.

can someone please post a link for the offline installer

i fix my post , i mean shortcut keys for protection enable/ disable for the HIPS :slight_smile:
