Editors' Review


AdFender is a wide-reaching piece of ad blocking software that plays well with Web browsers, P2P programs, and messaging applications. If you're looking to get less advertising content when using your computer, AdFender might be for you.


Product reach: AdFender extends ad blocking across Internet browsers and other software categories.

Saving bandwidth: The more complex advertising gets, the more of your Internet bandwidth ads are taking up. Video ads and ads with moving graphics can greatly slow down the time it takes a website to load, and can greatly increase the amount of bandwidth that site consumes. By blocking this content, you can speed up your browsing experience.

Low-resource blocking: Some ad blocking apps are resource hogs. The speed benefits you get by loading less online content are destroyed by the resource drain on your machine needed in order to run the blocking software. AdFender doesn't suffer from this problem, and runs lean and clean in the background without slowing down your PC.


Complicated operation: Although AdFender is quite well designed, the program can be a little complex at times, especially when it comes to the customizable rules.

Bottom Line

Overall, AdFender is an excellent choice for ad blocking software. It works well, doesn't slow your computer down, and works in almost all pieces of software that display website content. The complexity of certain features might be a bit overwhelming. But given enough time, you should be able to learn its ins and outs.
