Your browser opens the Visual Tracking Web page.
When Visual Tracking is finished, it displays a visual representation of
where this communication originated and contact information for the
owner of the IP address.
Stop Internet communication with Block Traffic
The Security Center and the Security Monitor include a Block Traffic button
that lets you immediately halt any communication between your computer
and another. This can be a handy way to limit any damage to your
computer if it is attacked, if a
Trojan horse is sending personal information
without your permission, or if you inadvertently allow an untrusted person
to access files on your computer.
When this option is active, Norton Personal Firewall stops all
communication to and from your computer. To the outside world, it appears
that your computer has completely disconnected from the Internet.
If you want to block all traffic into and out of your computer, Block Traffic is
more effective than simply using your Internet software to disconnect.
Most Internet programs can automatically connect without any input from
the user, so a malicious program could reconnect when you are away from
the computer.
w
Block Traffic is meant to be used as a temporary measure while you
address a security problem. If you restart your computer, Norton Personal
Firewall automatically allows all incoming and outgoing communication. To
continue blocking traffic, click the Block Traffic button in the Security
Center or Security Monitor.
