The Acrobat Reader software has serious security problems that Adobe has expressed a lack of interest in correcting. It's recommended that you use xpdf instead, and report any bugs to the very responsive maintainer.
Can you provide some links/refs or brief description of the security problems? What are they? I understand that PostScript can contain virii as its a full programming language but PDF is less that that. What can it do thats nasty?
