Hi. I can't block facebook using host file. I've already tried the different WAYS to block facebook using  hostfile. I've already tried putting '0.0.0.0' instead of '127.0.0.1', I hope someone will help me. thanks! Here's my Code:

# Copyright (c) 1993-1999 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# ADDITIONALLY, COMMENTS (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
#      102.54.94.97     rhino.acme.com          # source server
#       38.25.63.10     x.acme.com              # x client host

127.0.0.1       localhost

127.0.0.1   www.facebook.com
