# This script is an interface between mod_security and its
# ability to intercept files being uploaded through the
# web server, and ClamAV

# by default use the command-line version of ClamAV,
# which is slower but more likely to work out of the
# box
$CLAMSCAN = "/usr/bin/clamscan";

# using ClamAV in daemon mode is faster since the
# anti-virus engine is already running, but you also
# need to configure file permissions to allow ClamAV,
# usually running as a user other than the one Apache
# is running as, to access the files
# $CLAMSCAN = "/usr/bin/clamdscan";
