Understanding Anti-Virus on the ReadyNAS 6.10.2

Hello,

I have a new 626X ReadyNAS I am setting up for a small business.  I have enabled anti-virus on the shares I am creating.  I see from the docs that anti-virus only scans new files that are created using SMB.  I ran a test robocopy to put some files on the ReadyNAS device.  Afterwards, I noticed in the logs that some files were flagged by the Anti-virus scanner.  The message was "System: Antivirus scanner found a threat (threatname) in the file filename.  Please delete the infected file soon".  So, is there no auto quarantine for the AV scanning?  Is it up to me to keep a keen eye on the logs and manually monitor the found threats and delete files myself?  The docs speak of an app called Anti-Virus Plus, but I do not see that as an available app in the Apps tab.  Thanks!
