LibreOffice Writer: exported pdf & virustotal

[vasa1]

A user of LibreOffice Writer (Linux) exported an odt file as pdf and then uploaded it to virustotal.com for scanning. The organization to which she plans to submit the pdf file requires a "green" pass from virustotal.com.

I tried to get a green pass with the simplest of pdf files generated by LibreOffice 5.2.2 (Linux, Lubuntu 16.04) but couldn't. (It's nothing to do with a specific odt file.)

Taking the same odt file, opening it in Abiword 3.0.1 (a Linux word processor) and using "save as pdf" produces a pdf file that gets the green pass.

Here's a bit of information from the scan results for the LibreOffice pdf file:

The file being studied is a PDF document! The document's header reveals it is using the following file format specification: %PDF-1.4.

And here's information from scanning the pdf file generated by Abiword 3.0.1:

The poster would like to stay entirely with LibreOffice. Is there any way to tell LibreOffice to exclude the "open action" when generating the pdf file?
