I have a script that lets the user upload text files (PDF or doc) to the server, then the plan is to convert them to raw text. But until the file is converted, it's in its raw format, which makes me worried about viruses and all kinds of nasty things.

Any ideas what I need to do to minimize the risk of these unknown files. How to check if it's clean, or if it's even the format it claims to be and that it does not crash the server.
