I know that Norton is not for everyone but, if you are in the market for NIS2007 (with a free upgrade to NIS2008), this is one of the better offers going around at the moment, especially now that this deal has expired: http://www.ozbargain.com.au/node/2593
There is no cash-back to mess around with, no 3-PC minimum. Just $19.99 for the software and the 12 month subscription.
Heh, I like the Norton is not for everyone comment. I strongly dislike the anti-virus software in that it tends to overtake your computer. NIS is great for those people who are wary of the internet and the nasties that can be bestowed upon you.
