EDIT: Resolved very quick. We’ve just finished scanning of our website, and malware scanner reported file wp-content/plugins/purge-varnish/images/purge16x16.png If you open that file in text editor, you’ll notice some Javascript although it’s PNG file. Please let me know why this file contains suspicious JS. Everything else is great.

Initially had some issues with this plugin working properly, so I contacted the plugin author. He was extremely friendly and very fast to respond, and he added some code to fix my issue. Plugin works perfectly now with WP 4.8 and Varnish 5, and I’m very happy with it. I’d recommend it over the other Varnish plugins at this point, because it works with Varnish 5 and most others seem to be stuck on 3 or have limited support for 4.
