Do you have any specifics on what Drive does? Any examples of it fixing embedded virii? Or is this blind assumption?

I assume they mean "upload to drive and use the web based reader to view the PDF," not "upload to drive and download it again"

And what special sauce does the web preview use? At some point, someone has to actually parse and process the data. I feel like on a tech site like Hacker News, speculating that Google has somehow done a perfect job of preventing malicious PDFs beckons the question: how do you actually do that and prove that it's safe? And is that even possible in perpetuity?
