It would help if you told us about your network setup. Do you have a router? if so blocke facebook there

Thanks, I used the very simple host file, it works fine and smooth.

Hi there
Most decent Routers in their security set ups allow you to block IP addresses.

This is IMO a better solution as this will work with ALL computers connected to your network --wirelessly or via a cable --whether Windows, Mac or Linux.

You also don't have to do anything if you re-install the OS either

Pic enclosed of Netgear router --others are much the same I'd guess.

You can also establish rules etc etc.

IMO blocking via the Hardware setup on the router is far better as a knowlegeable user could easily get round the Hosts file restriction by using a "Proxy" to access blocked sites if you've only done it in software.

Using Content filtering on the hardware would be much harder to "break" as the user would have to logon to the router in order to change anything. Hopefully you've secured THAT password.

The best way of all actually is to ONLY allow your users to connect to the internet THROUGH YOUR OWN PROXY but this needs a bit of set up and organisation.

Failing that I'd use the ROUTER's HARDWARE blocking mechanism.

The logs will also tell you what IP addresses were used so you can tighten up any "After the fact" security breaches too.

This is not a secure way but you can add a line to C:\Windows\System32\drivers\etc\hosts like this:

Code:

# Copyright (c) 1993-2009 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

# localhost name resolution is handled within DNS itself.
#    127.0.0.1       localhost
#    ::1             localhost

0.0.0.0 facebook.com
0.0.0.0 www.facebook.com

Or get Windows Essentials: Other Programs - Microsoft Windows

It didn't work, I added the web address and the E-mail address on 2 separate lines so the browser cna still acces the web site.

It didn't work, Netgear router here.
I added the web address plus the E-mail address.

I started receiving "persistent and harassing" spam from a new web social service "nirvam dot it", E-mail "nirvam at nirvam dot it".
They are sending me two and even three mails every day it doesn't matter if I label it as spam in Gmail, they still keep coming.
I never visited their service nor I knew about them before getting their SPAM!
So simple question, how to I block them and eventually how do I report/blacklist them without dealing with them directly?

How can I kill them, how to report them for illegally harvesting E-mail addresses?

Several websites suggest disabling the Windows service named DNS Client if you are going to use a HOSTS file. You should also close your browser to make sure that the info that it has cached is cleared. Make sure that the browser has left RAM. This can take a minute or so after the Window has closed. Once you restart your browser, it should read the contents of your HOSTS file.

Restarting the computer (as carwiz mentioned) should clear the DNS cache too - if you opt not to disable the DNS Client service. Let's just hope that you won't be editing/restarting/testing the HOSTS file too often

If you can show us what your HOSTS file entries look like, then maybe we can spot any errors. I'm not sure how you can add/block e-mail addresses to a HOSTS file. More about that later*.

*I do not think you can block e-mails via the HOSTS file or via router settings. Those blocks are meant to prevent a computer on your network from getting data from a domain (a website like facebook.com). The e-mails that you are getting are coming to you thru Google's domains/website. If you blocked Google's mail servers, you could not get any e-mails.

It might be best to get a new e-mail address.
