Aha už to vidím, špatně jsem to pochopil s těmi IP adresami. Poslední dvě adresu (livechat.cz) se mi pořád nedaří blokovat a nevím co mám dělat :/ Vše funguje až na poslední. Současná podoba hosts

# 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

# localhost name resolution is handled within DNS itself.
