My plugin works for free. Unlike many of the security plugins that will sometimes find the threats but not clean them without a payment. My plugin will clean all the threats that it find without making a donation. You can even get new definition updates for free by manually clicking the update button without having made a donation.
I can see your point that the automatic updates is a “premium” feature but it is not necessary to clean your site, and the primary function of my plugin is to help people clean up the malware infections without having to pay a professional. Providing a free solution to the world of malware victims is the key component of my mission with this plugin. I truly feel that most people who choose to donate do so to appreciate my hard work and that is what enables me to continue working hard on this project. But I also fully support my plugin for free and there are many for users who gain the assistance they need from my work without ever making a donation. So I can appreciate you point of view but I will continue think of these contributions as voluntary donation.
P.S. The WordPress moderators don’t like people discussing anything to do financial matters on this forum so they might shut down this thread, but please feel free to pickup this discussion on my site gotmls.net ??
