TCP Monitor is a Windows program that will show you detailed listings of all TCP endpoints on your system, including names of remote servers and state of TCP connections.

Under Windows XP and newer TCP Monitor allows you to display all network processes and kill them, if needed. Additionally, you can use the "BlackList" option for controlling any TCP endpoints.

Sometimes Antivirus scanner reports that a program is infected with a Virus or Trojan, even when the program is not really infected with any malicious code. This kind of problem is known as "False Positive" or "False Alert", and it's quite a common problem in some of the password recovery tools and network tools on site.

If your Antivirus scanner reports that a program you downloaded from ITSamples is infected with a Virus or Trojan, please report about that to support (at) and specify the name of your Antivirus scanner, and the name of the Virus/Trojan that it detects.
It's also recommended to contact your Antivirus company, and ask them to fix this "False Positive" problem.

This utility is a standalone executable.
When you start TCP Monitor it will enumerate all active TCP endpoints, resolving all IP addresses to their domain name versions. You can use a toolbar button or menu item to toggle the display of resolved names.

By default, TCP Monitor does not to do update, but you can use the Stop/Start Autoupdate button to start autoupdating and the Settings dialog to change the rate. Endpoints that have different states are highlighted in different colors; those that are established are shown in light green, listening endpoints are shown in yellow, e t.c.

Additionally, you can save TCP Monitor's events to a file using the Save menu item (or appropriate toolbar button).
