Free Anti-virus for Mac

Now is the time to install anti-virus for Mac if you haven't already done so. With more widely occurring attacks on the Mac coming to light, the need for anti-virus on Mac OSX has risen substantially. Symantec have recently brought out a free option called iAntiVirus. It doesn't have the full capabilities of paid-for anti-virus but joins some other free Mac anti-virus tools such as ClamXav and Sophos Home Edition.
