i think i need professional help with the Comodo Firewall.
I’ve been running Comodo Firewall v8.4 (only the firewall aspect, no AV) alongside Avast Antivirus on Windows 7 x64 for about 4 years now - without any major problems or compatibility issues.
However, some time ago I needed to uninstall Avast Antivirus and after having Avast uninstalled, the Comodo Firewall service doesn’t start up anymore.
On each and every boot Comodo Firewall shows the following error-popup twice:
“Comodo Security Agent could not be started”
Having a look at the windows-services then shows that the comodo security agent service is not running and trying to restart/start the service always stops/ends with the error: “the service did not respond in a timely manner”.
I spent many days trying to fix this error (I tried the whole procedure, uninstalling avast and fixing this error, many times the past year) but I always ended up restoring a complete OS hard-drive backup, because nothing seems to fix this issue. I want to continue to use the comodo firewall, but once this error shows up, there is NO point of return. the only fix is restoring a hd backup.
Even when i finally managed to completely uninstall the firewall and then tried to reinstall comodo firewall v8.4 or even the latest live verion 10.x (version doesn’t matter after v6.x), the error “Comodo Security Agent could not be started” shows up again on every boot.
To give you a glimpse of the struggle i had, I will enumerate some of the things I’ve already tried to fix the issue:
i uninstalled Comodo Firewall from the control panel / software. - it did not uninstall the firewall-software, just the online installer! (this really needs to get fixed too!) so the error was still there, the software was still installed.
i then manually searched the original firewall offline-setup.exe and removed it with the setup menu. The Firewall then was gone, the startup popup-error was finally gone. however, some remnants were still there. f.i. the registry keys in HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\services\CmdAgent. CmdAgent and its subkeys seem to be corrupted and cannot be deleted by any user/admin/system-account. Either it’s really corrupted or it’s a deep-in-the-system rootkit-like security function to protect the software - i don’t know. But it’s not really completely gone. Reinstalling any version of Comodo Firewall v6.x - v10.x then leads to the same error message on boot again.
I also tried the “Official Comodo Uninstaller v18.104.22.168”. One time after I had already uninstalled the firewall via the setup.exe - one time before I had uninstalled the firewall via setup. Both with the same outcome: “Comodo Security Agent could not be started” shows up again on boot whenever I install a comodo firewall again.
I then tried to install comodo firewall after i had:
- no AV products
- other AV products than Avast
without any differences in the outcome.
- I tried to install the complete Comodo Internet Security Suite, with AV and all the annoying unnecessary stuff - the same result “Comodo Security Agent could not be started”. In fact i tried installing any combination possible, it doesn’t matter it just won’t work.
to sum things up: i’m finally able to uninstall avast antivirus and comodo firewall, however, and that is the major problem here, I cannot install comodo firewall again and use it because on every boot the “Comodo Security Agent could not be started”.
I’m struggling with this issue now for over a year and it cost me many days of time and nerves trying to fix it. And yet it still doesn’t work. As long as both, Comodo Firewall and Avast Antivirus are running and neither one are being touched or uninstalled, everything works fine. But when i try to uninstall the Antivirus or the Antivirus tries to automatically update itself, hell is breaking out.
Please, if someone qualified is able to help me with other stuff than the usual steps I’ve already tried, it would be very appreciated!
