How to modify the hosts file?
Where is the original hosts file?
The original hosts file is located here:
C: \ WINDOWS \ system32 \ drivers \ etc \ hosts
What does it contain?
It should contain this if it is intact:
---------------------------------------------------------------------------------------------------
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 on an individual line. The IP address should be placed# In the first column followed by the corresponding host name.Address# IP and host name should be separated by a space.## Additionally, comments (such as this one) may be inserted on individual# Lines or following the machine name. They are indicated by the# '#' Symbol.## For example:## # Source server 102.54.94.97 rhino.acme.com38.25.63.10 x.acme.com # # x client host
127.0.0.1 localhost
-------------------------------------------------------------------------------------------------------
If you have the same text as above, it is clean, but it does not serve much!

Now let's do something useful, add sites to block:Select this: (note that within a tablulation (TAB) between 127.0.0.1 gromozon.com)
127.0.0.1 gromozon.com127.0.0.1 xearl.com127.0.0.1 td8eau9td.com127.0.0.1 mioctad.com127.0.0.1 mufxggfi.com127.0.0.1 uv97vqm3.com127.0.0.1 coeds.com *127.0.0.1 lah3bum9.com *127.0.0.1 cvoesdjd.com *
Once completed, your file should be like this:

Obviously you can add all the addresses you want.
There are also lists of hosts made all ...Be careful though, if your hosts file becomes large, it may be a problem with the service ClientDNS of Windows that would duplicate (which puts a 99% svchost process in your Task Manager), therefore, caution ....
We just have to disable this service if you wish to use a large hosts file:Start / Run / type services.msc / search the right column ClientDNS / set "disable"
Example here: 26,000 entries.
