Did you uninstall normally, then boot into Safe Mode? At that point make sure you ran the CIS removal tool which is compatible with Windows 8, and removal tools for any anti-malware utilities which used to be installed on your computer but are now removed. Also, while in Safe Mode, ensure that the firewall driver has been removed.
Then reboot into normal windows and install CIS.
Even after doing all of that does the Firewall still not work?
Before restoring the old image you could probably wait a bit and see if anyone else has any thoughts. Sorry, at the moment I do not have any further suggestions, but that does not mean that others won’t.
I am on stand by waiting for your list of installed security and maintenance software.
When trying a clean installation make sure no other left overs of previously installed security software are around. This is an important step in Chiron’s guide. Then run the CIS clean up tool in Safe Mode.
Then as a finalizing step of the uninstall. Sometimes it happens that the Inspect driver is still present and needs to be uninstalled.
How to uninstall the CIS firewall driver when it stays present? Look up the properties of the network connection, select the Comodo Firewall driver and uninstall it. See the attached image.
I was very aware of Chiron’s guide, specially for what I never test before.
So I made it twice, one before creating this post, and one after, when Chiron said me to follow his guide (which I followed twice )
But I never found any driver left. So when I saw your post, I open this priority box to finally see this driver, but I haven’t any driver, even if the firewall is still installed.
Maybe this is the reason ?
The Inspect driver did not get installed on your system. Try installing the driver using the Have disk route (Disque fourni…). You can find the inspect.inf, inspect.cat and inspect.sys in the installation folder of Comodo Firewall.
