Did you wonder what triggered me write this article? Yes, I too fell prey to these free plugins. A few days back, I was desperate to download a very famous premium plugin from a nulled site and after installing it on my blog I got to know that the plugin was infected and it redirects my blog to a spam blog. I immediately disabled the plugin and checked for the code that caused the redirection in plugin files. After an hour I found the code and immediately removed it [ I don’t use that plugin anymore].
This incident taught me very important thing. Never trust nulled WordPress plugins and themes. However many of you might want to use those nulled or free plugins and themes for God’s Sake, If you are one of them then read the remaining article.
