In addition, if you're looking for protection for an iPhone or iPad, don't expect much. Even the two suites that offer apps for iOS devices -- Trend Micro and Webroot -- don't offer much more than very basic protection through their own built-in browsers.
As for which of the suites is best, they're all so different that there's no true overall winner. My favorite was Webroot SecureAnywhere because of the suite's simplicity and excellent protection, and because its Web dashboard showed detailed information about all of the covered systems, as well as recommendations about how to fix problems. But Webroot doesn't include Mac protection.
If you're looking for Mac coverage in addition to security features for Windows PCs and mobile devices, the Norton and McAfee offerings are your best bet. Although Trend Micro offers a good sets of tools and a well-designed, easy-to-use interface, its Mac support is limited. Norton and McAfee have a better balance between comprehensive protection and ease of use.
However, Trend Micro costs $47 less per year than McAfee All Access, which costs $50 less per year than Norton One. So if you're budget-minded, Trend Micro is an affordable compromise that offers some OS X protection, even if its OS X protection isn't as complete as that offered by the more expensive suites.
