What is this about?
Avast, Norton, and AVG each offer a paid subscription product called AntiTrack that is sold for one purpose: to hide the “digital fingerprint” that advertisers and data brokers use to identify and follow you from website to website.
However, independent researchers have repeatedly questioned whether any product can actually do this. Indeed, published research suggests that certain common forms of fingerprint protection can actually increase the user’s privacy risk.
Zimmerman Reed is investigating whether consumers who paid for these subscriptions received the protection they were promised.
Am I eligible?
You may qualify if all of the following are true:

- You paid for a subscription (and/or a paid renewal) on or after July 27, 2022, to one of these products:
- Avast AntiTrack
- Norton AntiTrack
- AVG AntiTrack
- You bought or kept the subscription at least in part because of what the company said about protecting you from tracking or hiding your digital fingerprint

Note that if you only used a free trial and were never charged, you likely do not qualify.
What Is a “digital fingerprint”?
Every time you visit a website, your browser hands over dozens of small details about your device: your screen size, your time zone, which fonts you have installed, how your graphics hardware draws an image, and more. Individually, none of these identifies you. Combined, they often form a profile unique to your device.
AVG’s own marketing tells customers that with enough of this data, websites can be 99% sure who you are, whether or not you are logged in.
Stopping it is genuinely difficult. A study presented at the ACM Web Conference in 2025 examined the built-in protections of five major browsers and 18 anti-tracking add-ons. It found that five of the 18 add-ons failed to provide the protection they advertised, and concluded that no fully workable defense against canvas fingerprinting, one of the most powerful techniques for fingerprinting, currently exists. Earlier research published at the USENIX Security Symposium found that products which feed false information to websites can often be detected doing so—and that the real information can sometimes be recovered anyway.
We are investigating whether anti-fingerprinting techniques are able to deliver what AntiTrack sellers promised to their users.
