I'm going to toss this out there again.
If virus definitions are built on a "known" virus and there are none currently for a Mac, then what definitions are you running? Even huristics requires a known virus before they can be functional in any capacity. Windows viruses simply can't run on a mac so using those are pointless. All this hype is so that some of these companies can sell software. I was/am (windows developer) a Windows user and I have had my Mac connected directly to the WEB (no firewall) and have never gotten a virus or malware. Don't install torrent garbage and you will be fine.
Bottom line, you are still tying up resources for something you don't need at this time.
Lastly, comparing UAC to UNIX root privlages is like comparing your local jail to Alcatraz. UAC is MS's way to try and catch up to what UNIX has pretty much had since inception.
