CUIC is an independent non-profit organization. This means that we act for or on behalf of consumers and have no commercial interests. We litigate in the Netherlands under collective action legislation. CUIC is an initiative of Privacy First and None of Your Business (noyb), two leading privacy organizations that have been successfully fighting and litigating to ensure an actual data protection for many years.

Do you have or did you have Avast anti-virus software on your computer, laptop, tablet or smartphone at any time between 2014 and 30 January 2020?

Avast provides a world-famous anti-virus software. Especially 'security extensions' for browsers (Chrome, Safari, Firefox and Edge) and browsers. To offer your 'maximum security', Avast promoted that you turn on these virus filters.

Avast's applications stopped viruses. However, at the same time they collected a huge amount of user data. Avast's US subsidiary Jumpshot sold this user data to anyone willing to pay for it.

So, instead of protecting you, Avast harvested your data to sell on to third parties. Your data can now roam everywhere and be used for many purposes you were not made aware of

We will hold Avast accountable for this gross violation of privacy.

Progress of Avast claim

Here you can see what point we are at in the collective action against Avast. At every new step in the procedure, we will update the timeline above.

  • Invitation for consultation

    We invited Avast to enter into discussions about their behavior and seek an amicable solution for all affected parties so that legal proceedings might be avoided. Avast replied that it did not want to enter into negotiations.

  • Issuing writ of summons

    Since the invitation for consultation did not yield the desired result, we will go to court and we filed our writ of summons on March 27, 2024. In order to be strong already at the court case starts, we are calling on as many people as possible who live(d) in the Netherlands to join us. Did you have an Avast browser extension with anti-virus software between 2014 and January 2020 Then sign up for this case. sign up for this case.

Who is it relevant for?

In the period from 2014 to 30 January 2020, did you have Avast anti-virus software on your computer, tablet, phone or laptop or were you using Avast's internet browsers and/or internet browser extensions? Then join our collective action: we demand compensation for those duped by Avast's privacy breaches. This is on a no cure, no pay basis: therefore, if you do not receive compensation, joining costs you nothing. In this way, you are also helping to ensure that companies act more fairly: no use of your data without your knowledge and consent, and no misuse of user data for your own gain. Not now and not in the future. Through lawsuits like this, we want companies to not only hear this but also feel it, financially and in their reputation.

More about our approach

As a collective, we take on companies and organizations for privacy violations. We claim compensation for those whose privacy has been compromised and try to modify the behavior of companies and organizations in breach of privacy regulations permanently. For justice and a data-safe world, in other words.

The conditions to participate

To participate in the collective action against Avast, you must live or have lived in the Netherlands in the period 2014 - 30 January 2020 (the “Relevant Period”).

You must have had one of the following browsers or browser extensions with Avast anti-virus software on your computer or that of your children in the Relevant Period: Avast Online Security, AVG Online Security, Avast Secure Browser, AVG Online Security extension and the AVG Secure Browser.

No cure no pay: participation free of charge

CUIC Foundation aims to make participation free of charge. We believe that users of Avast antivirus software should be compensated in the event of successful proceedings. The up-front costs of the case are financed by an independent litigation funder, Omni Bridgeway, on a 'no cure no pay' basis. Only if the case succeeds, Omni Bridgeway is entitled to a percentage of the compensation to be received by the victims with a maximum of 25%. If the case does not succeed, you will not owe anyone anything.

Why is privacy protection important now more than ever?

Privacy is a fundamental right that has never been more important to protect. The speed in which development of technological possibilities allow damaging violations faster and with more impact than ever before. Suppose a stranger asks you to hold your phone for a moment and sees and uses all your emails, photos, messages, connections, interests and apps to his own benefits, mainly selling them to anyone who wants them. Including sexual preferences or orientation, health and religious beliefs. This is in fact what happens all too often. We find this an extremely uncomfortable idea.

You have the fundamental right to be protected from such far-reaching data recording, trafficking in your data, and ramshackle data security by companies and the government. Unfortunately, that right is still too often violated. CUIC fights for these rights and discourages (potentials) violators. We hold companies accountable for this, to make them and others stop violating these fundamental rights.

Collective action

Collective action is gaining ground in the Netherlands. This is necessary because many organizations regard privacy as a nuisance instead of a fundamental right. Your right not to be digitally tracked everywhere, digitally as well as physically, for example; or the right not to have your data traded, is too often fiddled with. It is almost impossible for individual consumers to effectively protect their privacy. Legislation makes collective action possible and with it we want to make companies that don't want to listen feel it. We do this through strategic litigation.

CUIC subscribes to the Claim Code. This is a governance code for foundations whose aim is to represent collective interests. The Claim Code ensures that our conduct aligns with the interests of those affected by privacy infringements; it guarantees that CUIC puts the interests of the collectively disadvantaged first.

Logging in with/without IDin identification

We use IDin identification for the login process. IDin runs through banks, but we get absolutely no bank details. Why did we choose IDin? Similar court cases have shown that the courts look closely at whether someone applying for a class action lawsuit really exists and lives in the Netherlands. We do not want to run the risk of our case against Avast breaking down on this. With IDin, it is possible to conclusively prove that everyone who registers is actually a person living in the Netherlands resident in the Netherlands.

In addition, as a foundation, we have the highest standards of privacy. By using IDIN, we do not store your data. We only store the fact that you are identified. This way we have proof of your support, but not all kinds of personal data somewhere.We currently see this as the safest way of working, and the most economical in the amount of data we ask/store.

In fairness, we did find this a dilemma: as secure as it is, we understand that not everyone is comfortable with IDin being run by banks. In addition, there are some banks that do not support IDin for their customers, because it demands a lot from them in security and too few customers use it.

Logging in without IDin verification

For those unable or unwilling to use IDin verification, we offer another solution. You can then apply via a form (the 'Participant Agreement without IDin'). You can obtain this by sending an email to info@cuic.eu stating that you want to sign up without IDin. We will then send you via e-mail the form that you can complete, sign and mail or post to us. send. Naturally, we will handle your data with extreme care, as you can also read in our privacy statement
