So I decided to try out an mobile phone app that lists open ports of devices on a network and saw that my sister's laptop (which I got her a week ago [windows 10]) has port 31337 open (listed as Elite) and this struck me as strange since all system protocols run on ports below 1000.
Googling it I found it is associated with back orifice hack tool.
Running tcpview on her laptop shown that port to be used (listening) by "system" for TCP and for TCPv6, which meant that I couldn't see which executable runs it and I couldn't end the connection.
After avast didn't discover the virus I switched to windows defender who found one hack tool, but this wasn't the thing that was using the port.
Any help with solving this is welcome.
