# Remote clamd support
# If you're running a dedicated clamd server, you can instruct clamdscan to use
# it instead of the local daemon (which doesn't even need to run). To use
# this you need to create a 'clamd.remote.conf' with:
#
# TCPSocket 3310
# TCPAddr clamd.example.com
#
#
# Enable connecting to a remote clamd service to conduct all file scanning
# offload from local system. This requires that clamdscan binary be available
# to the local system.
#
# Files being scanned are effectively piped to remote daemon, this can be very
# bandwidth intensive.

# [ STATISTICAL ANALYSIS ]
# This is a beta feature and as such should be used with caution.
# Currently, this feature can have a substantially negative impact
# on scan performance, especially with large file sets.
##
# The string length test is used to identify threats based on the
# length of the longest uninterrupted string within a file. This is

# that produce very long strings without spaces (e.g: base64)
