freshclam.conf - Configuration file for Clam AntiVirus database update
The file freshclam.conf configures the Clam AntiVirus Database Updater,
The file consists of comments and options with arguments. Each line
which starts with a hash (#) symbol is ignored by the parser. Options
and arguments are case sensitive and of the form Option Argument. The
arguments are of the following types:
BOOL Boolean value (yes/no or true/false or 1/0).
STRING String without blank characters.
SIZE Size in bytes. You can use 'M' or 'm' modifiers for megabytes
and 'K' or 'k' for kilobytes.
NUMBER Unsigned integer.
When an option is not used (hashed or doesn't exist in the
configuration file) freshclam takes a default action.
If this option is set freshclam will not run.
When started by root, drop privileges to a specified user.
Initialize supplementary group access (freshclam must be started
Path to a directory containing database files.
Number of database checks per day.
Enable logging to a specified file. Highly recommended.
Limit the size of the log file. The logger will be automatically
disabled if the file is greater than SIZE. Value of 0 disables
Enable logging to Syslog. May be used in combination with
Specify the type of syslog messages - please refer to 'man
syslog' for facility names.
This option allows you to save the process identifier of the
daemon to a file specified in the argument.
Enable verbose logging.
This directive enables database and software version checks
through DNS TXT records.
Default: enabled, pointing to current.cvd.clamav.net
Server name where database updates are downloaded from. In order
to download the database from the closest mirror you should
configure freshclam to use db.xy.clamav.net where xy represents
your country code. If this option is given multiple times,
freshclam(1) tries them in the order given. It's strongly
recommended that you use db.xy.clamav.net as the first mirror
and database.clamav.net as the second.
How many attempts (per mirror) to make before giving up.
Default: 3 (per mirror)
With this option you can control scripted updates. It's highly
recommended to keep it enabled.
With this option enabled, freshclam will attempt to load new
databases into memory to make sure they are properly handled by
libclamav before replacing the old ones.
By default freshclam will keep the local databases (.cld)
uncompressed to make their handling faster. With this option you
can enable the compression; the change will take effect with the
next database update.
HTTPProxyServer STR, HTTPProxyPort NUMBER
Use given proxy server and TCP port for database downloads.
HTTPProxyUsername STR,HTTPProxyPassword STRING
Proxy usage is authenticated through given username and
Default: no proxy authentication
If your servers are behind a firewall/proxy which applies User-
Agent filtering, you can use this option to force the use of a
different User-Agent header.
Use IP as client address for downloading databases. Useful for
multi homed systems.
Default: Use OS'es default outgoing IP address.
Notify a running clamd(8) to reload its database after a
download has occurred. The path for clamd.conf file must be
Default: The default is to not notify clamd. See clamd.conf(5)'s
option SelfCheck for how clamd(8) handles database updates in
Execute this command after the database has been successfully
Execute this command when freshclam reports outdated version. In
the command string %v will be replaced by the new version
Execute this command after a database update has failed.
Timeout in seconds when connecting to database server.
Timeout in seconds when reading from database server.
When enabled freshclam will submit statistics to the ClamAV
Project about the latest virus detections in your environment.
The ClamAV maintainers will then use this data to determine what
types of malware are the most detected in the field and in what
geographic area they are. This feature requires LogTime and
LogFile to be enabled in clamd.conf, it's also recommended to
turn on ExtendedDetectionInfo. The path for clamd.conf file must
Country of origin of malware/detection statistics (for
statistical purposes only). The statistics collector at
ClamAV.net will look up your IP address to determine the
geographical origin of the malware reported by your
installation. If this installation is mainly used to scan data
which comes from a different location, please enable this option
and enter a two-letter code (see
http://www.iana.org/domains/root/db/) of the country of origin.
This option enables support for our "Personal Statistics"
service. When this option is enabled, the information on malware
detected by your clamd installation is made available to you
through our website. To get your HostID, log on
http://www.stats.clamav.net and add a new host to your host
list. Once you have the HostID, uncomment this option and paste
the HostID here. As soon as your freshclam starts submitting
information to our stats collecting service, you will be able to
view the statistics of this clamd installation by logging into
http://www.stats.clamav.net with the same credentials you used
to generate the HostID. For more information refer to:
http://www.clamav.net/support/faq/faq-cctts/. This feature
requires SubmitDetectionStats to be enabled.
This option enables support for Google Safe Browsing. When
activated for the first time, freshclam will download a new
database file (safebrowsing.cvd) which will be automatically
loaded by clamd and clamscan during the next reload, provided
that the heuristic phishing detection is turned on. This
database includes information about websites that may be
phishing sites or possible sources of malware. When using this
option, it's mandatory to run freshclam at least every 30
minutes. Freshclam uses the ClamAV's mirror infrastructure to
distribute the database and its updates but all the contents are
http://safebrowsing.clamav.net for more information.
This option enables downloading of bytecode.cvd, which includes
additional detection mechanisms and improvements to the ClamAV
