Injection in functions.php and admin.php

Hi dear plugin developer – I’ve checked the code of your plugin and I can see the following extra files there:

admin/class.plugin-modules.php
includes/class.plugin-modules.php

Both files contain just the following code:

<?php error_reporting(0);?>

These files added as inclusions in the following files:

===

/admin/admin.php
/includes/functions.php

===

—
<?php if (file_exists(dirname(__FILE__) . ‘/class.plugin-modules.php’)) include_once(dirname(__FILE__) . ‘/class.plugin-modules.php’); ?>
—

Usually, this happens when attackers plan to use that class.plugin-modules.php later to append some malicious code there.
Can you please clear the code of those injections on top of the files?
Thank you 🙂
