    Try this steps carefully:

    When CPF service is running, the registry protection is active.

    Boot to safe mode - hold F5 during boot and choose Safe Mode.
    In safe mode remove the folder: "C:\Program Files\Comodo\Firewall".
    You can use this reg file (http://www.sendspace.com/file/d2wpgl) to delete reg keys or you can do it manually:

    Windows Registry Editor Version 5.00

    [-HKEY_LOCAL_MACHINE\SOFTWARE\ComodoGroup]

    [-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Management\ARPCache\Comodo Firewall]

    [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
    "Comodo Firewall"=-

    [-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Comodo Firewall]

    [-HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\LEGACY_CMDAGENT]

    [-HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\LEGACY_CMDMON]

    [-HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\LEGACY_INSPECT]

    [-HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\CmdAgent]

    [-HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\CmdMon]

    [-HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Inspect]

    [-HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_CMDAGENT]

    [-HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_CMDMON]

    [-HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_INSPECT]

    [-HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CmdAgent]

    [-HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CmdMon]

    [-HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Inspect]

    [-HKEY_LOCAL_MACHINE\SYSTEM\Software\Comodo]

    If you are unable to connect to the internet and have the comodo firewall installed. You will want to try uninstalling the Comodo Firewall, then restarting your computer completely to rule out the firewall as being an issue.

    If you are unable to connect to a network share, unable to share files or unable to use internet connection sharing(ICS). Check the 2 configurations below to see if one will help you setup the comodo firewall. If the configurations below fail, you will want to try uninstalling the Comodo Firewall and restart your computer completely to rule out the firewall as being an issue.

    To run Comodo on your server with ICS Enabled - In order to do this you need to allow svchost and the system processes to access to the network zone. Then you need to allow the internet zone to access the network zone. Then you need to allow the network zone to access the internet zone.

    To run Comodo on your network in order to share files and folders - In order to do this you need to allow svchost and the system processes to access to the network zone.
