 AdGuard for Windows is an easy-to-use tool that blocks annoying banners, popups, video ads, and trackers. But that's not all: it helps you save traffic, load web pages faster, and protect your computer from undesirable and potentially malicious websites. AdGuard also protects you from phishing websites and keeps your kids away from inappropriate content.

 Once you start AdGuard for Windows, you will see the main screen of the app. Its most noticeable detail is the _enable/disable protection_ button. Also, on this screen you can monitor blocked ads, trackers and threats statistics, find out the current version of the app or update it. Furthermore, there are four tabs in the upper right corner: _Settings_, _Support_, _License_, and _About_. Each of these is worth talking about separately.

 ### Ad blocking
 
 This is the main module of AdGuard for Windows that removes ads from the websites you visit and from the apps installed on your device. To filter out advertising and privacy-threatening content such as banners, popups, or trackers AdGuard uses different filters — groups of rules with a similar purpose written with a [special syntax](/general/ad-filtering/create-own-filters).
