Malware warning | WordPress.org

I scanned my website with Quttera and found out some malware, parts of them in the independent analytics files.

After scanning and deleting some of the infected files, we finally discovered that the malware came from this plugin: independent-analytics

Once the cleanup was complete, we re-installed this plugin and scanned again, this time Quttera only showed one warning:

FILE: wp-content/plugins/independent-analytics/vendor/symfony/console/Terminal.php
