No.
I've been a Norton user since my 386SX days and have seen the Norton products "dumbing down" every year. It's also aging a bit - its DOS roots need some updating. (I've owned and used a number of Norton/Symantec products and versions over the years: NAV, Utilites, Navigator, Backup, SystemWorks, Ghost among others.)
I purchased Norton SystemWorks 2002 a few years ago, but never installed it, so I gave it to a friend and installed it on his WinXP computer. I realized the evolution of Norton Utilities and NAV to the various incarnations of Norton SystemWorks made the product suite easier for the average PC user, but the overhead was getting out of hand and the level of customization available had declined.
I originally installed the first release of SystemWorks on my 1999 P3 running Win98, but turned off a lot of the product's features. I've since upgraded it to SystemWorks 2003 (and Win98se), but I decided the product was not what I wanted for WinXP.
When I got an XP system last year, I skipped SystemWorks and purchased and installed NAV 2004 instead. I turned off many (if not most) of the automatic features including Auto-Protect. I don't need the extra features, nor do I want the overhead of useless junk (to me). Moreover, I discovered that simply disabling a feature does not always work in NAV 2004! Instead, one must turn the feature on, then drill down through the options menu(s) and uncheck the sub-feature's individual boxes and then turn the feature off.
So I now have NAV 2004 as I want it without the extras I do not need including Auto-Protect. On another note, I've been using computers in one form or another since 1965, including working as a mainframe programmer/sysprog/sr. analyst for 18+ years. I have only gotten 1 virus (and no trojans, worms, or browser hijacks) in all those years. Granted, 1965 TTY's and 75/110 baud acoustic coupler modems didn't get viruses, but still, I practice safe computing.
