ClamAV® is an open source antivirus engine for detecting trojans, viruses, malware & other malicious threats.
clamav-trademark.pngon QPKG Start

it automatically download latest virus database
and immediately start a scan on your user space "/share"
all infected file are moved automatically inside /opt/ClamAV/quarantine

logs files : /opt/ClamAV/log
config files : /opt/ClamAV/etc
database saved/update : /opt/ClamAV/DB

all binary : /opt/ClamAV/bin (not forced in $PATH, no interaction with the official Qnap it use different socket/PID)

including : freshclam / clamd / clamscan / clamsubmit / clamav-config / clambc / clamconf / clamdtop /clamonacc

if you want change command behavior on your need to modify the clamscan line inside : /opt/ClamAV/

all has been cross compiled from source with all libs shared as dependencies
