I have some PDF files given to me and I want to know how I can be sure that these are not infected with a virus, etc. I'm not too familiar with what security issues I should worry about with this file type and could not find a good answer with some searching online.I scanned the directory of files with MSE (no problems found) and then I generally only open other people's stuff (ie PDF's) in a sandbox.I have the latest update for Adobe Acrobat.I assume that anything with a URL in a PDF should not be clicked on.Is there anything else I can/should do?Thanks!
