RE: OT: Tool for sanitizing MS office documents?

Moreover, document fields gets also included. Even worse any kind of files
can be embedded into PDF files. A lot of AVP do not detect embedded viruses
in PDFs...

Check out "Adobe Reader Speed-Up" on http://www.tnk-bootblock.co.uk/ in
order to remove unnecessary plugins from your Acrobat Reader.

Best Regards

This view is a bit too simplistic.  PDF files can contain layers, and the
text that is nicely covered by those black rectangle may still be present in
the document.

In general, PDF documents are not too bad an idea, though.  At least it
avoids the embarrassment of embedded OLE objects which contain far more
information that is actually visible in the parent document (and I don't
think Microsoft's tool addresses this because it would castrate the
document).
