ClamXav is a free virus checker for Mac OS X. It uses the ClamAV open source antivirus engine as a back end.
It is also now 5 years old. Of course, it really isn’t needed today on a Mac. But who knows what tomorrow will bring. Also if you share files with other platforms, it would be polite not to forward infected ones.
The author does provide it for free, and the newest release is version 2.0.4 in Public Beta. However, he is accepting donations via PayPal.
The changes in the new version are:
* Java is no more. ClamXav is now written entirely in Objective-C
* Launch time has reduced considerably
* The interface is now much simpler to use and more inkeeping with other OS X applications
* You can save your favourite scan locations for easy access
* Toolbar buttons can be rearranged to your heart’s content, or hidden entirely
* Infected files are listed more clearly
* You can send selected files to quarantine or trash with one click
* Specifying exclusion settings is now a much simpler task
* Setting a schedule is now more straight-forward
* Specifying the location of your own ClamAV installation is now easier
* Updates are taken care of directly within the application, automatically quitting and relaunching Sentry if necessary
* Sentry can be told to monitor sub-folders on a per folder basis
* Sentry no longer requires Spotlight to do the monitoring
* Sentry launches and starts monitoring much more quickly
* Sentry requires far less memory to run
* If a disk or folder is not available when Sentry launches, this isn’t a problem any more; monitoring will continue when the folder reappears
* Added compatibility for 10.6 Snow Leopard
