I was just wondering... If someone asked you to ensure that a large PDF file is clean of any evil things.
How would you do this.
(assume the file passed virus scanner, and it legitimately contains some JS content - so scanning source for existence of it is not enough).
This is a curiosity/non urgent question for those with time on their hands to share their most secret white hat ways.
