Blocking Unwanted Parasites with a Hosts File
Special Note: new Windows 10 users ... the MVPS Hosts file installs just fine, no need to make any changes. Simply follow the instructions for Windows 8. What it does ... You can use a HOSTS file to block ads, banners, 3rd party Cookies, 3rd party page counters, web bugs, and even most hijackers. This is accomplished by blocking the connection(s) that supplies these little gems. The Hosts file is loaded into memory (cache) at startup, so there is no need to turn on, adjust or change any settings with the exception of the DNS Client service (see below). Example - the following entry 0.0.0.0 ad.doubleclick.net blocks all files supplied by that DoubleClick Server to the web page you are viewing. Using a well designed HOSTS file can speed the loading of web pages by not having to wait for these ads, annoying banners, hit counters, etc. to load. In case you're wondering ... this all happens in microseconds, which is much faster than trying to fetch a file from half way around the world.
