I had installed Norton Utilities a couple of months ago, for reasons that are irrelevant and unremembered at the moment. Anyway, I decided I didn't need it, so I deleted the application file, the preference pane, and all the ancillary files I find in the Library folder. And still I get a "Norton Utilities detects a new version of Mac OS X" dialog box whenever I log on (same with other users on this computer). It's hardly a major inconvenience (just have to hit Return) but what can I do to get rid of this with minimal hassle. Thanks.
