uninstall comodo firewall (error)

Hi. I uninstalled Comodo firewall with ccleaner.
Everything seemed to go okay until the end when some error message popped up about the agent or something.
I restarted the computer, but it still shows up in ccleaner and the uninstaller still opens. I get about 3 seconds into the uninstallation before it says “The specified account already exists”.

How do I remove this program from my computer (Going to Norton 360)

I recommend you use GeekUninstaller “first” to uninstall Comodo Firewall : http://geekuninstaller.com/geek.zip

then you can use Force Uninstall Tool;

I suggest to run the Force Uninstall Tool
while booted in Safe Mode.

When installing a new security program always make sure there are no left overs of programs that were installed in the past by running clean up tools for them. A list can be found here at the Eset website: ESET Knowledgebase .
