I know that MS Word documents can contain dangerous code. I know that gif and jpgs are safe.
How about PDF, is that safe?
And, is there any easy way that I can make sure that an MSWord document does not contain executable code. I need to do this on the server.
What we are trying to do is allow people to attach files to their data on our site. We do not however want to allow then to attach things that may carry viruses and trojans and things?
