Test your Antivirus and Firewall.

Let me say. NIS Firewall can block GRC test if you turn off the silent mode. But surprisingly PC Tools cannot block leaktest. There have been some arguments that it is a FP by GRC test. But don't know why this FP occurs specifically with PC Tools Firewall.

Im rather inexperienced with PC tools firewall, I prefer Outpost/OA to it.
(PC Tools FW never worked on my PC due to some driver issues)

Anyway, the default mode (silent) of the Norton firewall is somewhat unnerving at times. You never know what is allowing/blocking, that is why I prefer a firewall with a strong HIPS.
