Schmitz Mark Allan has issued [1]ClamXav 2.8.1 with a big change for the Mac virus scanner ' it's no longer free. Now released through Canimaan Software Ltd. (of which Allan is the owner and lead developer), ClamXav costs $29.95 (though it's discounted by 25 percent to $22.46 for a limited time). Allan [2]notes that 'by charging for ClamXav I will finally have the resources to devote to it and give it the attention it deserves,' including regular updates and fast turnaround of bug fixes. Version 2.8 brings Yosemite-inspired Retina toolbar icons, ensures ClamXav and Sentry correctly exclude the quarantine folder from scanning, updates the ClamAV engine to version 0.98.7, fixes a bug with the animated Dock icon that caused inordinate amounts of CPU usage, correctly honors the exclusion settings in ClamXav's preferences, and improves stability (particularly for Mac OS X 10.6 Snow Leopard).
