"Alternative to TCPview"

Pros: It's very easy to use and gives detailed information. Depending on your personal habits and taste, you may prefer this over Sysinternal's TCPview.
Other Thoughts: Download and try it. As for me, I use it daily. It's a good tool to make sure there are no ports open that may put your computer in danger.
