If you think that there might be something strange going on with your PC you should check what it is connected to. There may be a chance that you have some programs that are using your internet connection in the background without your knowledge.

To see what is going on you can use the netstat command from a command prompt window:

  • Open the Start menu and enter “cmd.exe” in the Search box.
  • When the results display, right-click on cmd.exe and select Run as administrator from the popup menu.
  • At the command prompt, type the following command and press Enter.
netstat -abf 5 > whatsgoingon.txt

Wait about two minutes and then press Ctrl + C to stop the recording of data.

  • Open whatsgoingon.txt to see all processes that have made an internet connection in the last two minutes. It also lists which processes connected to which websites.

If you see processes or websites that you do not know check them out in Google. If you think what you have found might be a bad program, get rid of it!
