Those of us that have been around since the dawn of the computer age know full well AV companies are responsible for many generations of viruses to peddle their products with fear mongering. Many of these companies have been caught numerous times but the suckers keep on giving them money.
Personally I wouldn't trust any product associated with the Norton franchise. After what what they did with Disk Doctor and many thousands of people lost their data to their shoddy tool I'd never use this product or any other even if it was given away.
ClamAV is a good free tool if you really even need to care about winblows viruses being passed along accidentally. I couldn't care less if I did pass along any winblows viruses to my winblows clients. They gave it to me in the first place and they can have it back.

On the positive side Symantec refunded my money without question and was very understanding.
I don't like to bag Symantec as I have used their products for years, but this version of Norton's was not up to scratch and unlike their other products. If Symantec fix Norton's I will purchase it again and give it another try.

So far it works fine. Just for fun I saved one of those zip attachments that I got on some junk mail that's supposed to be from UPS, and it detected the virus right away and removed it from the file.
The only downside is if you have it regularly scanning you hard drive, the "Norton Missed Tasks" background app eats up CPU cycles, so I turned that feature off and only have it scan my downloads folder.
I'm not expecting any viruses, but so far it has not messed up my Mac in the least. If I didn't know it was installed, I wouldn't know. It's very unobtrusive.
@Wizard2; it's easy to uninstall, it didn't write files all over the place, and we aren't using PCs, so maybe you are thinking of Windoze?

Configure your connection manually and avoid the bloatware.

What I said was Comcast offered this package, and since they were using it at Sony Music, I figured I'd give it a try. It works perfectly, and even helped my wife when she stumbled upon a fraudulent website when she was looking to order something.

Have you ever tried removing this stuff from a computer?
It's a world of hurt -- miss just one of hundreds and hundreds
of files and prefs it seeds throughout your harddrive -- and
the bugger re-replicates itself. It's baaaack like a movie zombie.
Most viruses and malware on Mac OS X require admin user approval
before they install or active.
The solution is simple - be vigilant and careful. NAV at best is an
expensive, messy, buggy lesson. At worst, it will damage your PC.

I had some trouble right after updating to Snow Leopard and I got an email reply, and a call back to assist me. They were professional and knowledgable. NAV did not waste a lot of system resources or give a lot of false positives.

That so called uninstaller is passable but misses dozens of files you need to manually remove. Provided you even know where to look.
Want proof? Use an Uninstaller tool to monitor the installer and then use the installer. Now count on all your fingers and toes or until you run out of digits how many files were left behind.

One thing I notice is that ClamXav seems to detect email viruses that NAV completely misses. Can someone clarify whether the signatures in NAV for Mac are OS X specific, and do not include Windows viruses? Do you need to purchase the "dual protection" version of NAV in order to get Windows virus signatures included in your scanning?
Is it possible that ClamXav is giving me false positives, or have a missed a configuration setting for NAV?
