Avast AntiTrack is a tool that stops various types of tracking on the Internet, giving you more anonymity online.There are many different types of online tracking: For example, when advertising companies track users across all websites using browser cookies, this is called ad tracking. Websites and advertisers can also track your online behavior across the Internet to compile a profile of you and your online habits. Avast AntiTrack puts a stop to these invasive forms of online tracking by disguising your "digital fingerprint" and the unique data used by advertisers to identify you. It also tracks and removes tracking cookies so no one can see your searches.
