How could u not know u had a firewall? ...very odd anyway in answer to your question look in the system tray, if you do have a firewall running there will likely be an icon in there showing it, if not then check what programs are installed on you puter, it should be fairly evident if one is a firewall. Just out of interest, do other people apart from yourself install stuff on your puter, because I fail to see how you can not know you have a firewall when u must of installed it in the first place.
