My niece brought a cheap mac laptop for her studies, which is version 9.2 (I think). We have just connected to the internet (In New Zealand). But can't easily find a anti-virus, firewall, and spyware for her Mac. I found ClamAV, but only for later versions of Mac. I have set up dozens of system utilities for Windows, but know nothing about Macs. Any suggestions where to get such software and how to install them? Thanks...
