PDF Script is shown in Google Results

Using PDFCrowd, we have pages that are showing up in googles results that are the actual script used to generate the PDF:

https://www.google.com/search?sourceid=chrome&ie=UTF-8&q=T.+Brad+Davey

The 3rd item is the PDF Script.

Is this a common issue? Are there things that we can put in place to prevent this from happening?

Thanks,

Hello,

one option is to add the following line to your robots.txt

Disallow: /PDF3.html

Please note that it may take some time before the pages are removed from the Google index.
