Is There A Programe Out There That Can Detect And Manage All My Firewalls?

When I try to log onto an IM or P2P network I get a message telling me that a firewall is blocking access to the internet. I’ve disabled all firewalls known to me but I still can’t get on, Is there a programe out there that can find firewalls on my computer that I don’t know about or I may have forgotten about?

Multimedia?

What is the most practical and most simple programe for building multimedia programs and is there any site to learn in it free on internet? Thanks.
