hi guys, i just want to know how i can block some websites? because in comodo firewall only can block IP address 
I Googled and found this sight for you. You type in the domain name and it gives you the IP address. Google is your friend.
You can block a web site to: Firewall > My Blocked Network Zone > Add a new adresse > a hoste name (here you can type your host name i.e. www.kaspersky.com)
It works!
