when AVAST secured line is ON :
using the utorrent configuration assistant to test the network,
it indicates that the port is not open.
and dowload does not work

when AVAST secured line is OFF :
using the utorrent configuration assistant to test the network,
it indicates that the port is OK.
and download is working
