Last week during a continuing education session on running a law practice, our speaker said he hasn't used antivirus software on the Mac systems in his office for quite some time -- inferring, of course, that Macs are more secure than machines that run Windows.
I'm not here to argue which operating system is more secure. I've never used a Mac, so despite what I've heard, I don't know. From what we've seen in the tech press recently though, I do know that as the popularity of the Mac grows, it becomes an increasingly larger target for malware.
One hacker used his blog to keep readers updated on his efforts to create a worm that would infect the Mac OS X, and he claimed success until July, when the blog was abandoned. And even more recently, whispers of "half-baked security" accompanied the release of Mac OS X 10.5, also known as Leopard.
If security concerns are growing, is it wise to go without antivirus software on your Mac? Probably not.
