The first thing is to locate the file named "hosts" in your system files. There is no file extension on this file. On Windows 2000 it is located in {X}:\winnt\system32\drivers\etc folder, where {X} is whatever drive your OS is located. Next download the attached zip file extract the _host file and copy it to this folder. Finally, to make this easy, extract the included Batch file from the zip named hosts.bat and save it to a place where it will be secure. The batch file is what enables/disables this function.
Once all the files are in place, simply double-click the hosts.bat file to toggle the effect. Now, when you go to a website that has Adsense or Chitika none of the ads will appear. They have been remapped to the loopback address, 127.0.0.1 whch disables the ads. To re-enable the ads, just double-click on the hosts.bat file and they will toggle back on.
No longer do you have to worry about someone getting on your coputer and clicking away on your ads (unless you left the hosts.bat file lying around).
Both files have been zipped below.
