    Reduced CPU usage of main app
    You can run multiple scans at one time
    Complete integration of all component parts (Main app, Sentry, Scheduling, Reports)
    Smart source list which automatically displays all available volumes.
    You can now have per-source-item scan settings
    …along with different exclude settings per scan item
    You can enable/disable quarantine per scan item
    … and even enable/disable quarantine during a scan
    We’ve added copy & paste support for “exclude file settings” (between source list items as well as copying files from Finder)
    If you quit ClamXAV, the scan will continue
    All-new ClamXAV menu item which shows progress of all current scans and database updates
  • There’s so much more, but I think you get the gist. It’s all new!
