What Programs are Accessing the Internet

You only have a couple of websites open on userr screen and yet the data activity light of the modem / router is constantly flashing indicating that one or more programs are actively uploading or geting data from the Internet.

How can user easily find out which programs on userr computer are accessing the Internet and what websites are they connecting to?

You have quite a few options. If user are on Windows 7 or Vista, user can use the built-inPerformance monitor utility to see a list of all running processes that are currently accessing the Internet.

Alternatively, if user are on a different version of Windows or want something less complex, try TCPEye 1.0. This is a free network monitoring utility that creates a self-updating list of all processes that are currently using userr network connection.

What makes TCPEye a bit different is that it also lists the websites / servers that the programs are communicating with and the location (country) where those servers are located. Most other network monitoring tools only mention IP addresses and thus it is up to the user to determine the underlying server name.

If user notice an unwanted connection or a suspicious entry in the TCPEye log, just right click to end the process.
