Virus Complacency -- Though there are few Macintosh viruses (especially in comparison to the PC world), in the last few weeks I've received several reports of virus-infected CD-ROMs or files (the most recent one an upload caught by alert Info-Mac archivist Michael Bean). Although all the viruses were old and easily handled by John Norstad's free Disinfectant 3.6, I believe many Macintosh users have been lulled into complacency by the minimal virus problems of late. In addition, many people have become Mac users in the last few years, and thus missed the era when most Macintosh viruses appeared. Most existing Macintosh viruses aren't particularly dangerous, but it's always worth running an anti-virus program. For more information on the different viruses, read Disinfectant's excellent online manual by selecting Disinfectant Help from the Apple menu. If you feel like spending money (we at TidBITS recommend and use Disinfectant), check out commercial virus protection software like Symantec AntiVirus for Macintosh and Datawatch's Virex for Macintosh.

Mac OS X Services in Snow Leopard
Mac OS X Services let one application supply its powers to another; for example, a Grab service helps TextEdit paste a screenshot into a document. Most users either don't know that Services exist, because they're in an obscure hierarchical menu (ApplicationName > Services), or they mostly don't use them because there are so many of them.
Snow Leopard makes it easier for the uninitiated to utilize this feature; only services appropriate to the current context appear. And in addition to the hierarchical menu, services are discoverable as custom contextual menu items - Control-click in a TextEdit document to access the Grab service, for instance.
In addition, the revamped Keyboard preference pane lets you manage services for the first time ever. You can enable and disable them, and even change their keyboard shortcuts.
