Most websites use tracking systems to monitor visitor behavior, which allows them to obtain statistics and other data for marketing purposes. The Anti-tracking feature in Avast Online Security & Privacy allows you to see which tracking systems are used by the websites you visit and stop them from tracking you.
When you visit a website that uses tracking systems, the number of trackers is visible on the
