Display PostScript implementations are becoming increasingly more common. A PostScript program running in such an implementation would not be overly restricted in the amount of resources it could affect. The potential for trojan horses or viruses in PostScript is large. Practically noone looks through the code before previewing or printing a document from a non-trusted source, escpecially if it looks like it came from a document production system. -- _.John G.
