Not exactly, you could just plug the cord on your internet, but I see you still want to browse.
Like the user before me has already said, try using COMODO Firewall, it's free. It will ask you to decide whether or not you want to allow a program to access the internet when it's about to connect.
It's very useful and that program is held in high regard around here.
