Consider you have a suspicious pdf file that might contain malware. Would it be sufficient to either:
open the pdf file in a virtual environment and let the pdf viewer or pdf-creator program "print-to-file" a new clean pdf file from the original one?
use a program to extract only the text from the contaminated file and save only text to a *.txt file?
If both are insufficient, are there any tools like "NoScript" for pdf? Or else, to protect against pdf malware - other than a virtual machine?
