title: Does installing Node.js under Windows have any security implications?
body: <p><strong>Here's why I'm asking</strong>:</p>
  
  <p>In order to use the <code>lessc</code> compiler under windows, I had to install Node.js and NPM based on this guide: <a href="http://lesscss.org/#getting-started" rel="nofollow">http://lesscss.org/#getting-started</a></p>
  
  <p>So basically, I just:</p>
  
  <ol>
  <li>Downloaded and installed Node.js from <a href="http://nodejs.org/" rel="nofollow">http://nodejs.org/</a></li>
  <li>Ran and installed <code>lessc</code> using <code>npm install -g less</code></li>
  </ol>
  
  <p><strong>Detailed question</strong>:</p>
  
  <p>Are there any security implications I should be aware of? Does Node.js open any ports? Does it run in the background? Does it auto-update?</p>
