2 firewalls at a time

One of my cousin say I should not have 2 firewall, is it really? and if it is, how do I make it com0do?

You can not have two ACTIVE Firewalls. If you have more than one in the computer, it is deactivated. Are the windows Firewall, Comodo that you have ?

No if it is turned off but is a bit much for the stupid PC something here. But had to switch comodo out with Kerio and have then found out I should not have 2 on but it's easy enough to delete comodo? So this is 100% gone?

You must delete one of your firewalls. If you do not, it ends up in the conflict. You keep it running most of you. Remember it is different from computer to computer.

Download Kerio

Remove the network jack / disable the Internet connection.

Right-click the icon to Comodo at the clock and press "Exit".

Close now your antivirus, antispyware and other protection.

Go to Start - Control Panel - Choose "Add / Remove Programs" - Find "Comodo Firewall Pro" on the list and click "Remove."

Then, restart your computer - now Comodo Firewall away.

Install Kerio from the file you downloaded onto the desktop.

Ask final if there is anything you are in doubt.
