Finding out which process is causing the traffic should narrow things down. Open a command prompt window and type
netstat /b
The output will be something like this:

This reveals the process for every active network connection on your system. As you can see I'm running firefox, outlook, skype and internet exploder. jusched.exe is the Java update scheduler.
Alternatively, install Currports from Nirsoft.
Good luck,
Arthur
