  <p>If I deactivate Adblock Plus (1.9.3) the error message is gone. If I activate Adblock Plus the error shows up again, even if every other extension is deactivated. I am worried Adblock is not the problem, but makes the problem visible.</p>
  
  <p>Also a project I just finished got declined by Google Adwords with the reason "Malware". Im waiting for a callback from Adwords tech support for more details.</p>
  
  <p>I am worried that my system or browser is infected with some sort of malware which already found its way into my web projects. I have no idea what to do about it.</p>
  
  <p>I am running the latest Chrome on Yosemite 10.10.5</p>
  
  <p>Any suggestions?</p>
