With Macs you don't need to purchase software?
Anti-virus.. well.. I've personally never owned any, and I've been using PCs for a long time. I can't say I've ever been infected with a virus. I think it has something to do with me not surfing questionable websites or downloading pirated software or other questionable things. Also, not sure if you noticed, but they do sell
anti-virus software for OS X.
Anti-spam.. Are you saying Mac owners absolutely never get.. spam? Huh?
The software topic is related to malware. You do not (currently) require anti this&that software for OS X machines. For Windows it is the norm.
You add anti-spam software because that is a first line entry point for virus and other malware. I get my fair share of spam on OS X, but it is minimal as my service providers are clearly filtering for me. I can be fairly confident that even if I get some spam with malware, it will be targeting Windows and therefore will not be a problem for my OS X box.
Owning anti that&that software does not guarantee you won't get a hit with something bad, but helps. Especially those people who don't follow some basic rules to avoid it. That would be most Windows users. Most computer users are ignorant about computer security and since Windows is such a big target, they should be buying into what can protect their systems. As I mentioned earlier, there are some free alternatives.
As a side note. I've run Windows too at home for certain reasons. Only once can I say I had some naughty software on the box. It surprised the **** out of me since I knew I hadn't downloaded any e-mail to the box, didn't browse the net with it, and all incoming ports went through a router blocking everything to that box. I figured the trojan came with some legit software I had bought. So I'd suggest you at least try some of that free software to check up your system once in a while. I'll do the same for my Mac when it becomes an issue.
