I agree that Norton Anti-Virus and Virex are both very good. Yes, Mac's do get viruses from time to time and we are not exempt from viruses. It is just that there are so many more Win. machines out there, so most of the viruses are for Window's. Beleive me, if Apple had 90% market share, we would have many more problems with viruses. I have anti-virus protection on all of my machines. One other thing, since new viruses are being written every day, when you do buy an anti-virus program, remember to check every month for updates, or set your auto-update feature to once a month.

I've had Norton Antivirus and Utilities for many years now and not once have I had a virus show up. Now, I have used the Utilities numerous times, such as Disk Repair and Optimizer. Both have worked okay. Recently though I have had disk problems at work. Norton was useless. I just purchased the much-raved-about Disk Warrior. I have read in many places though that Norton is nothing compared to Disk Warrior. I'll find out soon. So you might want to look into Disk Warrior options before spending money on Norton. I agree with fletch though, better to have and not need than to need and not have.
