Adobe Print to PDF produces hundreds of open text files

I am helping one of our users who is encountering something strange on her PC. When she prints a document to PDF her computer will start opening hundreds of text files that all have an error message similar to the one below:

%%[ ProductName: Distiller ]%%
This PostScript file was created from an encrypted PDF file.
Redistilling encrypted PDF is not permitted.
%%[ Flushing: rest of job (to end-of-file) will be ignored ]%%
%%[ Warning: PostScript error. No PDF file produced. ] %%

I understand that this is likely because the document is encrypted, however on other machines it will simply create one log file and save it where the PDF had been pointed. What I would like to understand is why her device keeps opening these files, but never saves one. Is there a way to force adobe to not post these errors? On the occasion one happens I feel it would be better to get no warning than these hundreds of documents.
