 * Hi Susa38,
 * That sounds questionable. I did a simple default install, brought the files over
   via SFTP and found nothing like what you describe.
 * I found the following:
 * class-custom-sidebars-editor.php
    class-custom-sidebars-explain.php class-custom-
   sidebars-replacer.php class-custom-sidebars-widgets.php class-custom-sidebars.
   php
 * I created a simple sidebar and brought the files over a second time and found
   no change.
 * That might warrant some digging.
 * Best of luck,
 * Mike

 * Thanks a lot Mike. I do not know if you are member of the developer team of the
   plugin so I would like to corroborate this question.
    I know that this file is
   not normal on new installs. I would like to know if it’s an old version file 
   or some file that now is not in use but was installed by the plugin or not.
 * Please, Could some member of the developer team comment something about this 
   file?

 * Hey there Susa38,
 * Hope you’re well today!
 * This is definitely not a part of the plugin in the current version of it. I don’t
   recall having such file before as well but I’ll have to consult our plugin developer
   on this one just to make sure this wasn’t a part of some old versions.
 * It would also help if you could paste the code from that file so we can check
   it out. If there is just a few lines you can paste it here, otherwise please 
   use [http://pastebin.com/](http://pastebin.com/) and paste the link where we 
   can see this.
 * Looking forward for your response 🙂
 * Best regards,
    Bojan

 * I have revised the backups of my site and there is not this file in older versions.
   In 20 may 2015 someone insert this inside. I suposse a hacker but I’m not sure
   if it’s possible the system plugin made it. I think not propably by your words.
   
   I do not know if it was inserted by a plugin hole or by other raison
 * I can sendto you the code but I would like to send to you in private because 
   i do not understand the code and I do not know if it has some private information
   of my wordpress configuration.
 * Is it possible that I paste the code in pastebin.com in private mode and send
   to you an email with the password to see the code?
 * thanks

 * Hey again Susa38,
 * Such files shouldn’t have any sensitive data but I can’t say that for sure so
   it is actually a good idea to send it to us privately. Also this doesn’t mean
   that the hole is within Custom Sidebars plugin just because the file is placed
   there.

 * Thanks Bojan.
    I know that probably is not a hole from custom sidebars plugin.
   Only I comment this to help the developers of the plugin if it was the case.
 * I have sended to you the information on your contact form
 * thanks a lot

 * Hey again Susa,
 * Thanks for sending us code from the file, upon closer inspection this is definitely
   material for removing!
 * It contains eval that allows you to execute php so this might be used to make
   a hole in your site which can be later used for something. You can find more 
   info about eval here [http://php.net/manual/en/function.eval.php](http://php.net/manual/en/function.eval.php).
 * Please remove the file from your site.
 * Best regards,
    Bojan
