Conflict between Acrobat Distiller and Norton AntiVirus
MacFixIt reader Bob O'Driscoll describes a conflict between Norton AntiVirus and Acrobat Distller that has been confirmed by Symantec's technical support department:
"When trying to create PDFs from Word X files, I found that some files worked while others kept producing PostScript errors. This occurred when using the PDF button in Word, or when saving as a PostScript file and opening with Distiller. The PostScript file would however print correctly on a PostScript printer. I think the offending command was usually 'showpage'."
Turning off Auto-Protect in Norton AntiVirus 9 will resolve this problem. And in some cases, users can restart, turn auto-protect back on, and retain Distiller functionality.Resources

Yep, had the same problem creating most PDF files with Distiller 6 and
AntiVirus 9 Autoprotect on. Turned off Autoprotect and, bingo, every
PDF works. Think I may just leave it off for now.

(3 Comments)I found that I couldn't open System Preferences. Also, extensions, such
as .img, opened the wrong file. Immediately after turning autoprotect
off, the problem disappeared. I worked for several hours today, and
finally narrowed the problem to the latest Norton Antivirus coupled with
the latest Acrobat 6 version.
