I recently formatted my PC and have installed some new softwares on it. I found that my internet bandwidth usage is showing very high figures. I don't think I use so much of the bandwith and am feeling like some of the software I have installed is eating up the traffic. Is there any utility which checks the internet calls from my PC when I am online? I want to check any suspecious net reqests going out from my PC. If that utility also gives the name of the process which is issuing the request then it would be ideal.
