Official Comodo Uninstaller v3.1.0.55 Released

Hi All,
We are pleased to announce availability of Comodo Official Uninstaller that can be used if you can not uninstall Comodo Internet Security, Comodo firewall or Comodo Antivirus from Add/Remove or Uninstall section of Windows.

For 64-Bit Operating Systems:
http://download.comodo.com/cis/download/installs/ciscleanuptool/CisCleanupTool_x64_3.1.0.55.exe

For 32-Bit Operating Systems:
http://download.comodo.com/cis/download/installs/ciscleanuptool/CisCleanupTool_x86_3.1.0.55.exe

Few points:
1)
Before it continues un-installation, it tries to create system re-store point and in case it fails, it will inform user to create before continuing.

It will typically ask for re-boot twice. Edit: No longer ask for reboots on v3.1.0.55

If this tool still fails and you still think you have Comodo installed and can’t re-install, we would like you to report bug in bug report section, providing following log files as input in post:

  • You will find log in same folder from where uninstall tool was executed
  • You need to find all logs from Windows temp folder (Windows Key + R and then type in %TEMP%) of following format:
    cmdinstall.exe_.log.7z
    cmdinstall.exe_    .log
    COMODO *_uninstall.log

A broken uninstallation situation typically happens when you end up re-starting system in between installation or update or somehow abort the installation or update. We hope this tool will help remove Comodo in those critical situations.

To mitigate these problems in future, in Dec-2017 CIS release:

  • Before CIS installation, uninstallation and update, CIS will try to create system re-store point
  • We will also be shipping these binaries together with Comodo installation in Dec-2017 release.

Thanks

5

Yes.

6

Greeeat! So how to avoid users to uninstall CCS at the endpoint level?

7

Please check if you have test server entry in hosts file.

10

That was it. Thanks!

11

I had time to play with it. Its much better then the old version. I dont see any issues off hand, but will report if any found

12

This is a historical moment for Comodo!
Although terribly overdue… I know it’s going to become a well recieved tool! :-TU Thank you so much! :slight_smile:

13

I tried it. After quietly installed any antivirus, but the registry entries remain

14

Some registry residue may be there.

Could it uninstall successfully?

15

When reinstalling the CIS or installing another antivirus, there is no problem

16

Good.

17

The registry keys that get left behind can be removed without a problem. They are no longer protected by running processes of CIS nor are there user right limitations that will block you or your favorite registry cleaner from removing them.

Hello

On Win XP SP3 Comodo Uninstaller worked flawlessly with CIS 10.0.1.6223 (as a preventive measure Avast antivirus free has been temporarily disabled). Some entries found with CCleaner have been easily deleted without bad effects.
Installed Comodo Firewall 10.0.2.6420 via online installer. Everything works fine now. I’ve been waiting for a long time for an official uninstaller and this one seems to do a good job.
Thank you very much.

Today I had to use the 64-bit version of this uninstaller on a Windows 10 system that was crashing with a blue screen reporting a problem with cmdhlp.sys. This was right after Microsoft’s Fall Creator Update (1709). See https://forums.comodo.com/bug-reports-cis/bsod-windows-10-update-failure-of-cmdhlpsys-update-1709-1001629998-t121162.0.html;msg870145#msg870145.

Booting to Safe Mode (no networking), then running the Comodo uninstaller, then rebooting, I was able to recover. But my network connectivity wouldn’t work. It turned out that my network adapter was still binding to an entry called “COMODO Internet Security Firewall Driver”. Clearing its checkbox for that entry got me back onto the internet. Looks like the official Comodo uninstaller doesn’t do a thorough enough job.

Booting into safe mode without networking support is why it didn’t remove the firewall driver. The uninstaller could not see it being installed due to no network adapters being available or shown as installed when booting into minimal safe mode. I would have renamed cmdhlp.sys when in safe mode then booting normally, and renamed it back to cmdhlp.sys and run the uninstaller tool. Or boot into safe mode with networking.
