Netmon is a compact, easy-to-use network information utility. It displays infomation pertaining to the IP, TCP, UDP and ICMP protocols.

It's main purpose is viewing connections made using TCP and UDP protocols FROM or TO your computer.

This information may prove very useful in hunting trojans (or other suspicious activity) present in your system.
