It's a suite of functions from my ISP but appears to supplied by F-Secure
(one of the anti-virus makers). It does include traffic
monitoring/blocking,
web filtering, and a firewall. I cannot tell if it is a hybrid or not. I
will look
into whether or not the suite is a packaging of separate programs or if it
is
a hybrid.

The results of netstat include a local and foreign address. The local
address
includes a port, while the foreign has a port of 0 (most of the listening
sockets
appear that way). Is this significant? For example (many others removed):
Proto Local Address Foreign Address State

I will look into this.
>Have you checked whether the Windows Firewall is enabled?
The network connection does not have the firewall enabled (Advanced tab
on the connection properties).

I will look into this.
Thank you.
