The best is NONE. It's not required. OS X is designed now to provide built-in protection that is updated transparently to the user.
Helpful Links Regarding Virus Protection
An excellent link to read is Tom Reed's Mac Malware Guide.
Also, visit The XLab FAQs and read the FAQ on malware.
For general anti-virus protection I only recommend using ClamXav.

Kappy is absolutely correct, do not repeat do not install antivirus software on your iMac. The best protection you can off it is to run Software Update frequently, you can set that preference in:
System Preferences - Software Update

ClamXav to ensure that you do not pass on Windows viruses that you may have received via emails, to Windows users - but please read on:
There are many forms of ‘Malware’ that can affect a computer system, of which ‘a virus’ is but one type, ‘trojans’ another. Using the strict definition of a computer virus, no viruses that can attack OS X have so far been detected 'in the wild', i.e. in anything other than laboratory conditions. The same is not true of other forms of malware, such as Trojans. Whilst it is a fairly safe bet that your Mac has NOT been infected by a virus, it may have another security-related problem, but more likely a technical problem unrelated to any malware threat.
You may find this User Tip on Viruses, Trojan Detection and Removal, as well as general Internet Security and Privacy, useful:
The User Tip (which you are welcome to print out and retain for future reference) seeks to offer guidance on the main security threats and how to avoid them.

Actually, that discussion is about MacKeeper, and not really relevant to the current question.
Currently Being ModeratedDec 7, 2012 3:18 PM (in response to thomas_r.)
no disrespect intended - we did side bar into mackeeper in that thread but i started off along these lines
from basically the same point of mind as the op (thought this thread would help them - thats why)
Personnally at times I get confused on malware, anti-virus and phishing with all the discussions I have seen on the forums as well as when I attempt to read product information at given sites eg: clamxav sophos iantivrus etc.....So please allow me to ask the following question, even though macs really dont get virus's So assuming I have a mac in a pure mac environment what do these products actually do (1) Clamxav - does clamxav work as an antivirus does it protect you from malware does it protect you from phising does it protect you from trojans/worms (2) Sophos same questions (3) Iantivirus same questions Now assuming that I have a mac in a windows shared environment, what does each of these products do with the win relationship existing (1) Clamxav (2) Sophos (3) Iantivrus I have noticed that clamxav is recommended (why/what does it really do) and sophos primarily but i am seeing trending where Iantivrus works well to - but I never seem to find the answer to my question to make an informed decision to not use anything or to have something on my mac due to the fact that the product will protect me due to reason x...y...z.....and I feel it is the best product for myself.

if I were to pay for virus protection I would use Kaspersky
they seem to be ok on the pc platform Sophos on the other hand is the worst virus scanner I've ever
been exposed to it slowed the pc (windows) down to a crawl and never let most virus's pass

Don't judge by what you know from Windows. Kaspersky has abysmal detection rates on a Mac, according to the testing I referenced earlier, while Sophos has the best. Sophos also doesn't have much of an impact on a Mac's performance in my experience.

sidebar: thomas - thank you for the detection rate link.
as for Kasperski - windows side (i alternate KIS and Norton) two of them together are fantastic in keeping a win computer running clean and safe
as for Kas on the mac not a firm believer in the product yet (still feels and functions as a secondary product line) in my humble opinion
was surprised with intego

Unless you run one as on demand only you are asking for trouble, you should never have more than one resident AV
