Since there hasn't been a released MacOs X virus since 2006, you really don't need any. iAntivirus looks for the 7 Mac trojans and works quickly. ClamXav also checks for the 1,000,000+ Windows viruses, so it slows your Mac down. If you are paranoid about getting a virus (you have a better chance of your MacBook getting hit by lightning or getting stolen), either one will work for you.
The 7 Mac trojans are not viruses, they require you to download fake or illegal software and install them with your admin password.
