  • My problem is that I have no influence which reader is going to be used, I have to filter out the potential malicious files before they reach the target pc. Commented May 5, 2015 at 12:58
  • An upstream anti-virus scan is your best bet so answer such a requirement. But, you would be right to think that it will not be able to filter everything, all known and unknown threats (despite some of their claims...). That's why you need to implement in-depth defense and have some security implemented on the end-user desktop environment too. Commented May 5, 2015 at 13:03
  • No internet connection available, that is my second problem (otherwise I would have used the virustotal access). Commented May 5, 2015 at 13:13
  • I meant an anti-virus installed on a machine which will be in measure to scan the file before it is available to the end-user (installed on the mail or file server for instance). If there is no Internet access, a special care should be taken to apply offline signature database updates to the anti-virus. Commented May 5, 2015 at 17:36

    @WhiteWinterWolf I only use Chrome PDF to read pdfs do you think this is dangerous ? Could you clarify why one should not use browsers built-in PDF readers? At least on chrome it is sandboxed and can't touch your PC, and you can see PDFs from web without needing to download them in first place Commented May 6, 2015 at 2:40
