Antivirus program or malware checker or Google Ads claim that matomo.js or piwik.js are malware, what can I do?

In rare occasions, it has happened that a particular Antivirus program maker, or a Malware detection tool, mistakenly claim that Matomo JavaScript tracking code is a malware.

When this happens, you may experience the following symptoms:

• Visitor browsing the website(s) using Matomo may see messages from their antivirus or malware check tools for example `Malware was detected in the following file and it has been removed.`
• Google Ads campaigns may be blocked and stop running and Google asking to remove the Matomo JavaScript tracking code.

As the Matomo creators, we guarantee that the original JavaScript tracker file does not have any malware.
