In Preferences/ADVANCED SETTINGS, SecureAnywhere for MAC defaults to (1) "Scan for Windows threats" and (2) "Scan only for Windows file settings." There are no options for OS X threats or files.
Hi amilholland - No need to worry. Webroot will scans for Windows and Mac threats through the Webroot Intelligence Network. It will check Windows files that may be on the Mac for users that setup Boot Camp partitions/volumes.
