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.

[hidepost=1]

When you create a HOSTS file, you want each server specified to redirect to your own computer (always 127.0.0.1). So, what you’re telling the computer is to redirect all calls to one of these servers back to itself. The effect is that all calls to ads from these servers will be blank, thus blocking any potential threat.

It is important to note, too, that this is a very expansive list of ad services and spyware sources BOTH. Just because a particular server is listed here does not mean that that company engages in spyware. Just because they may place a cookie on your computer does not mean they are practicing in spyware.
