I was finally able to remove every trace of the Symantec "bloatware." The uninstaller does not do this. Make sure you back up your entire system (I recommend SuperDuper) to a Firewire drive prior to doing this. I also recommend booting into Safe Mode to run the removal operation.

I have used various Symantec/Norton products over many years and have been happy with them all until now. This product did not work on my MacBook Pro. It loaded okay but then wouldn't work, to include, recognizing it was on my Mac, wouldn't register, and wouldn't update. I was being overly cautious buying this product but when it would not work, I deleted it entirely from my Mac and returned it. Thankfully, Amazon's return processes do work. Save yourself a headache and your money -- do not buy this product for your Mac.

well, I'm in the middle of a month before my virus definitions subscription expires. so, Norton has pleasantly given me notices every frickin' day to remind me that they're expiring. you can't turn this off. it interrupts whatever you're doing, regardless if you have more important things to do. Their customer service is no help. This is like forced SPAM on an espresso blitz. so, think you'll like Norton? go for it. enjoy. no, really.
