For the first time since the release of OSX, Apple now recommends installing antivirus software on your computer. I am a Mac user in my personal life...and I for one had not yet installed any form of antivirus software on mine; why install the unnecessary? No that is not a shot at Windows...well maybe it is. After hearing the news that Apple now recommends installing it I went out and grabbed ClamXav and installed it right away. It is not the fastest program out there, but it is free and I am cheap. We all knew that the day was coming that our beloved Macs would be prone to viruses, so why hadn't we installed them before? There is still time to install just to be on the safe side. Check out the Apple recommendation here which also includes several options for an antivirus solutions.
