Get Rid of Norton!
Jack himself doesn't care for Norton products. In his opinion, they are bloated programs that interfere with normal system operation and don't do a very good job. In fact, it's been my experience that Norton Anti-Virus misses a lot of Viruses out there. Of course, YMMV, and Norton might work just fine for you. If so, stop here and don't read any further.
Jack makes good money fixing computers simply by uninstalling Norton Internet Security 200x, and installing Command AntiVirus or AVG and Tiny Firewall or Zone Alarm. NIS 2004 causes many problems, and is a 198MB installation! I have NO idea why it needs to be so large.
Jack's client supplied PowerBook G4 came with Norton AntiVirus on it. As it is now officially mine (It's not 'borrrowed' anymore), I wanted to uninstall NAV.
You need the original disk.
Don't have it, and the client couldn't find it.
As a public services announcement, I give you Mac OS X users the link to the Symantec Uninstaller, which removes any Symantec product from OS X, and is compatible with 10.3 Panther.
You can find it with Google, but it wasn't on the first few pages if you searched for 'Uninstall Norton AntiVirus OS X'.
