Re: Best antivirus for mac ML 10.84 ?
Hey, even Apple HQ got hit with malware earlier this year. Then there's emails and documents sent from other OSs that may unintentionally have something embedded that might not affect me on my Mac but cause a misery if forwarded along - so yeah, I use an AV program because I can and its no stress. If you want to live in a closed environment and do nothing but trade iWorks documents between other Mac users, swell - but otherwise, the bragging rights to Mac OS being the best AV is sketchy - and really, if it can be done for free with a minimum of fuss, what's the problem?
Its probably very worthwhile checking out AV-Comparatives - a fairly respected neutral organization that checks out a variety of OS antivirus programs on a regular basis - and its Mac Security Review. Its most recent one from August 2013. Some good stuff there.

For my part, I've been using the freeware Avast! on my Air since I got it. And yes, its quarantined a couple of things in that time. I note that it got a pretty good review in the AV-Comp reviews, so I am happy with that. Its got plenty of user choices if you don't want to go with the default (on mine for example, I've set it to check for updates daily at 9am, scans at 915am) - and the only real 'drawback' I have found is that after it scans, it leaves its icon in the Dock. I think this is meant to be a feature, as clicking it opens up its report (so you see if it found anything) and clicking OK removes the icon.
Hope this helps.
