Norton 360 is blocking me accessing the internet via a BT Wi-Fi Dongle

Finally, I can actually post a message. Norton 360 counts trying to set up my new BT Wi-Fi Dongle when I plug it in after installing its software as an intrusion and blocks it. If I look in the security history it is listed as such with no means given to unblock it. Without looking in the security history all you get is no internet connections available etc just as if it wasn't plugged in but in the device manager it says its correctly installed. Anyone any ideas on how to unblock it or should the information about the dongle have said its incompatible with Norton products like Norton 360 that contain a firewall? Its looking like BT Wi-Fi Dongles are incompatible with the Norton Firewall.
