Hello,
I need pro-help in this case. I'm struggling with this issue over one year already and tried many things many times, also with the help of the Comodo-Staff. We had no success so far.
I have a Windows 7 x64 OS and I'm running Avast Free Antivirus together with Comodo Free Firewall v8.4 (firewall only, everything AV releated is disabled). Both were running perfectly together with no problems over more than two years. For reasons I don't want to discuss here, i wanted to uninstall Avast Free Antivirus.
This is the main problem:When i uninstall Avast Free Antivirus and the uninstallation succeeded, Comodo FW isn't able to startup anymore. The "Comodo Security Agent could not be started"-error on boot prevents the Firewall from being started. The CmdAgent (comodo fw service) can't be started anymore on startup. This Error is FINAL. Once it is there, there has been NO WAY back fixing it. No uninstallation, no reinstallation, no different versions, no avast/comodo cleanup tools, no manual legacy driver removals, NOTHING fixed this error.
The only way is to restore a complete hard-drive backup.
The source of this problem seems to be Avast. Because only if i uninstall Avast Antivirus, this problem occurs.
Please, if anyone here is able to help with other things than the usual stuff, let me know!
And please also have a look at this comodo forum thread, where you can see all the attempts we already tried to fix this issue.
Thank you.
