Comment on Technical Support by SEO Dave.
I’ve released a Free Security Update/Upgrade of the Display Widgets Plugin which is called v4.0.0 and is malicious code free and extends the widget logic features.
I’ll be supporting the new version with new future updates: it’s not going in the WordPress Repository so I’ve added a custom update library (updates from my server not the WordPress plugin repository).
I also plan to release a premium version (on the above link) which will be an upgrade to the Display Widgets SEO Plus plugin, renamed to Display Widgets Plus Plugin (keep it simple).
Plan to add Woocommerce widget logic support to the premium version.
