Remove This Captcha Plugin Now!

I’ve recommended BestWebSoft Captcha in the past and now regret it after reading this article:

Looks like BestWebSoft sold the plugin and you need to remove this plugin right away and update all your plugins.  I do recommend that you have some kind of captcha on your login page for security and use at least the free version of the WordFence plugin.  I use Google Captcha (reCAPTCHA) by BestWebSoft

Stay safe, my friends!
