# LogFile must be writable for the user running daemon.
# A full path is required.
# Default: disabled
#LogFile /tmp/clamd.log
LogFile /var/log/clamav/clamd.log

# By default the log file is locked for writing - the lock protects against

# the daemon with --config-file option).
# This option disables log file locking.
# Default: no
#LogFileUnlock yes

# Maximum size of the log file.
# Value of 0 disables the limit.
# You may use 'M' or 'm' for megabytes (1M = 1m = 1048576 bytes)

# in bytes just don't use modifiers.
# Default: 1M

# Default: disabled (must be specified by a user)
LocalSocket /tmp/clamd.socket

# Remove stale socket after unclean shutdown.

# Note: disabling this limit or setting it too high may result in severe damage
# to the system.
