How to Completely Remove Comodo Firewall

Comodo Firewall is actually a wonderful program to help assist in the never-ending battle between nice friendly data and evil virus data. I’ve been using it and been very happy with it, but a few days ago, I encountered significant difficulty in removing this Firewall a previous version so that I could upgrade to the latest version.

Comodo is one of the more difficult firewalls to remove from a computer. Usually going through add/remove programs can not delete it completely. You’ll find traces still left in the registry and the actual firewall is still recognized by Windows Security Center, let alone an Internet connection. To get rid of them, you can follow the below instructions:

Method 1 (I take the deletion in Windows XP as an example)

1. Shut down all the unnecessary programs

2. Temporarily disable your Internet connection

3. Delete the folders and files below if they still exist. Most users will have C: as the default location for Program Files, if the location is in another drive, open it.

4. Go to Start – (right click) My Computer – Properties – System Properties – Hardware – Device Manager – View – Show Hidden Devices – Non-Plug and Play Drivers, and then delete all the existing related entries as below
