At today’s age with Internet connection availability becoming a common lifestyle companion, it’s practically impossible for your computer not having any program unknowingly accessing Internet in the background, as long as your PC is connected to Internet.

Even if you’re not running any web browser, IM client (such as MSN, Yahoo! Messenger) and email checker, chances are there will still be some programs running background scheduled jobs to check for software updates.

So, how do you know which exact program is actually communicating to the Internet?

I’m using NetLimiter 2. It’s available for Windows. The free version of NetLimiter 2 is featuring a simple monitoring tool, which is showing a listing of all programs currently requiring incoming or outgoing network connection.

Besides, you can also generate network traffic statistics of a program, for a particular date.
