General
What is Avast AntiTrack in Avast One?
Avast AntiTrack in Avast One is a privacy feature designed to help protect your identity from online tracking techniques. Avast AntiTrack inserts fake information into the data that makes up your digital fingerprint, changing the information that trackers and other third parties can see about you. It also removes tracking cookies and other tracking data from your browser.
What are the Avast AntiTrack browser extensions and why do I need to install one?
The Avast AntiTrack browser extensions are required to detect and block tracking activity across websites. You need to install the extension for each supported browser that you want Avast AntiTrack to protect. After activating Avast AntiTrack in Avast One, you are prompted to add the extension. For detailed installation instructions, refer to the following article:
- Google Chrome
- Microsoft Edge
- Mozilla Firefox
What is online tracking and how does it affect me?
Online tracking is the process of collecting information about online activity through analytics and tracking technologies embedded in websites. This information can be used to create a unique online profile, also known as a digital fingerprint, that allows advertisers and other third parties to identify and track individuals online. Online tracking can have the following effects:
- Advertisers may use information about online behavior to display targeted advertising.
- Certain websites may adjust the prices displayed for products or services that have been researched online, such as flight tickets.
- Websites may store personal information that could be exposed in a data breach and accessed or misused by third parties.
How is Avast AntiTrack different from an antivirus or VPN app?
Antivirus applications are designed to protect devices from security threats, such as viruses, trojans, and other malware, but they do not prevent online tracking. VPN applications are designed to encrypt the internet connection and mask the device's IP address and location. However, when using only a VPN, trackers may still identify a device based on its browser, device configuration, and online behavior. Avast AntiTrack is designed to disrupt digital fingerprinting and help prevent advertisers and other third parties from tracking online activity.
