I first started using Norton's antivirus software in 1994, I think. I won't support it any more. This software made itself a subscription product one day out of the blue without giving me a choice. I hope nobody will support their Mac version.

I believe Norton would be better of selling swim suites in the Antarctic. (The experts say, that in a couple of hundred years it will be warm there)

They make the viruses so they have (raison etre) a reason to be in existence. If there were no viruses they would have no reason to be in existence so they simply make them!

I shouldn't even give it a half star. Norton used to write good software MANY years ago in Classic, but then screwed up royally when OS X came out.

Does anybody even use their software anymore?

They are the persona that manufactures the viruses for us to digest. They haven't gotten around to OSX yet as it is far better to infect Windows as that is where the real money is.

I have removed so many Norton anti virus apps from school computers that come pre installed with no viruses found. In many cases after installing ClamXav, several viruses have been found. I regard Norton as a virus in itself - it invades a hard drive with no good purpose.

Hopefully all these antivirus companies will finally blow away with latest security measures of Mac OS X. Stop to sell your scareware! I believe most viruses are written by these companies themselves.
