ClamXav’s two-pronged approach helps it do as well a job as it does. The program allows you to put infected files aside in a specified quarantine location, then tear them and delete them as you see fit following the scan.
What makes ClamXav truly shine is its support base, as well as the fact that it doesn’t try to be overbearing within the OS X operating system, nor does it try to function without your permission and solve all your problems.
ClamXav is updated on a daily basis by a group of incredibly talented security engineers and distributed for free.
