TCPView Editor's review

If something on your system is running amok, or you think you might have a spy in your midst, or you're simply curious (or obsessive) about the inner workings of your network, give this simple program a look. TCPView presents you with a very simple interface that is appropriate to its purpose and relatively easy to use. You get a list of the TCP/UDP connections on your system, and the ability to interact with specific connections or the process that created them.

The list auto-updates as connections are created or destroyed, so you can see your network activity in real-time. If a particular program--or perhaps malevolent bit of spyware--is streaming data from your system, you'll be able to see it, and, with the handy context menus, either close the connection or end the process. If there's a lot of activity on your system, you can filter the list. You can also save the entire list to a text file, and alter the speed at which the list refreshes.
