A more drastic solution involves using a modified hosts file: click here
You can begin blocking ads and help keep yourself from being tracked by using the Hosts file with Windows and other operating systems.
What is the Hosts file, and how does it stop ads and tracking?
The Short Answer:
The short answer is that the Hosts file is like an address book. When you type an address like click here into your browser, the Hosts file is consulted to see if you have the IP address, or "telephone number," for that site. If you do, then your computer will "call it" and the site will open. If not, your computer will ask your ISP's (internet service provider) computer for the phone number before it can "call" that site. Most of the time, you do not have addresses in your "address book," because you have not put any there. Therefore, most of the time your computer asks for the IP address from your ISP to find sites.
If you put ad server names into your Hosts file with your own computer's IP address, your computer will never be able to contact the ad server. It will try to, but it will be simply calling itself and get a "busy signal" of sorts. Your computer will then give up calling the ad server and no ads will be loaded, nor will any tracking take place. Your choices for blocking sites are not just limited to blocking ad servers. You may block sites that serve advertisements, sites that serve objectionable content, or any other site that you choose to block.
A popup stopper will also help. As will a change of browser to, say, Mozilla Firefox.
