title: how do i use UPX safely?
body: <p>I am trying to reduce my application size with <code>upx</code> using <code>--lzma</code> compression method.</p>
  
  <p>But, whenever I use <code>upx</code> and scan my application after compress,  its shows that this application has virus. This is the virus result that comes up </p>
  
  <p><strong>Gen:Adware.Heur.RmTfWDj6fzli</strong></p>
  
  <p>If I scan the application before using <code>upx</code>, application is totally clean and no virus detected.</p>
  
  <p>How do I avoid this issue? </p>
  
  <p>I am using upx 391 from here <a href="http://upx.sourceforge.net/" rel="nofollow">http://upx.sourceforge.net/</a></p>
