Proc Net Monitor is a free network monitoring software that tracks the network activity of all processes in a system.

The software provides you with a detailed view of network activity by displaying all network-bound processes and TCP/UDP ports/connections opened by the selected process. It also includes a unique "Port Search" feature that lets you find processes that are using a specified port like 80.
With the online malicious process verification feature, you can scan suspicious processes using online services such as VirusTotal, ProcessLibrary, and Google. This allows you to identify any potential threats and take appropriate action to address them.
The color-based representation feature makes the identification of network-oriented processes easy by displaying them in red color. You can also use the sort feature to arrange the listed processes based on name, pid, path, company, TCP/UDP count, net connections, etc.
Additionally, Proc Net Monitor provides a right-click menu that makes it easy to quickly kill a process, view properties, online scan, etc. You can generate complete reports in HTML/XML format, and it includes both a portable and installable version.
This software is available on multiple Windows platforms including Windows XP, 2k3, 2k8, Vista, Windows7, Windows 8, and Windows 10. With all these features combined, Proc Net Monitor is one of the most effective tools to combat Trojans and spyware on your system.
