title: How to decrypt a javascript file
body: <p>I just discovered a virus in my computer that uses a .js file to attack. I opened the file in notepad to check out the code, but it is completely encrypted. I can see some data that makes sense (such as <code>bhynivmao.length!=4</code>), but the majority of the file is filled with gibberish.</p>
  
  <p>There is also an autorun.inf and even though I can see some of the <code>shell \open\command</code>, I am not able to figure out the rest of the gibberish that is present. </p>
  
  <p>Looks like both the autorun and the .js file are obfuscated the same way. Can someone please help me to get back the readable code? I am really curious to know how this thing works.</p>
