I am having problems with my copy of Norton Antivirus for Macintosh, v.2.1.1 (5), running on a Mac Mini, OS10.4.11, 1.33gHz PPC. I have not made any changes to this computer recently, but in the last couple of weeks LiveUpdate (v.5.1.2 (22) has stopped working on this application. It displays the message ‘Determining what’s available’, but gets no further than that. Any suggestions would be appreciated, thanks.
