       freshclam.conf - Configuration file for Clam AntiVirus database update tool


       The file freshclam.conf configures the Clam AntiVirus Database Updater, freshclam(1).


       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

       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.

       LogFileMaxSize SIZE
              Limit  the  size  of the log file. The logger will be automatically disabled if the
              file is greater than SIZE. Value of 0 disables the limit.
              Default: 1M

       LogTime BOOL
              Log time with each message.
              Default: no

       LogSyslog BOOL
              Enable logging to Syslog. May be used in combination with UpdateLogFile.
              Default: disabled.

       LogFacility STRING
              Specify the type of syslog messages - please refer to  'man  syslog'  for  facility
              Default: LOG_LOCAL6

       LogVerbose BOOL
              Enable verbose logging.
              Default: disabled

       LogRotate BOOL
              Rotate log file. Requires LogFileMaxSize option set prior to this option.
              Default: no

       PidFile STRING
              This  option  allows  you  to  save  the process identifier of the daemon to a file
              specified in the argument.
              Default: disabled

       DatabaseDirectory STRING
              Path to a directory containing database files.
              Default: /var/lib/clamav

       Foreground BOOL
              Don't fork into background.
              Default: no

       Debug BOOL
              Enable debug messages in libclamav.
              Default: no

       UpdateLogFile STRING
              Enable logging to a specified file. Highly recommended.
              Default: disabled.

       DatabaseOwner STRING
              When started by root, drop privileges to a specified user.

       Checks NUMBER
              Number of database checks per day.
              Default: 12

       DNSDatabaseInfo STRING
              Use DNS to verify the virus database version. FreshClam uses  DNS  TXT  records  to
              verify  the  versions  of the database and software itself. With this directive you
              can change the database verification domain.
              WARNING: Please don't change it unless you're configuring freshclam to use your own
              database verification domain.
              Default: enabled, pointing to

       DatabaseMirror STRING
              DatabaseMirror  specifies  to  which mirror(s) freshclam should connect. You should
              have at least one entries:  Now that CloudFlare is being  used
              as  our  Content  Delivery  Network (CDN), this one domain name works world-wide to
              direct freshclam to the closest geographic endpoint.

       PrivateMirror STR
              This  option  allows  you  to  easily  point  freshclam  to  private  mirrors.   If
              PrivateMirror  is  set,  freshclam does not attempt to use DNS to determine whether
              its databases are out-of-date, instead it will use the If-Modified-Since request or
              directly  check  the  headers  of  the  remote  database  files. For each database,
              freshclam first attempts to download the CLD file.  If  that  fails,  it  tries  to
              download  the  CVD  file. This option overrides DatabaseMirror, DNSDatabaseInfo and
              ScriptedUpdates. It can be used multiple times to provide fall-back mirrors.
              Default: disabled

       MaxAttempts NUMBER
              How many attempts (per mirror) to make before giving up.
              Default: 3 (per mirror)

       ScriptedUpdates BOOL
              With this option you can control scripted updates. It's highly recommended to  keep
              it enabled.
              Default: yes

       TestDatabases BOOL
              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.
              Default: enabled

       CompressLocalDatabase BOOL
              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.
              Default: no

       ExtraDatabase STRING
              Download an additional 3rd party signature database distributed through the  ClamAV
              mirrors. This option can be used multiple times.
              Default: disabled

       ExcludeDatabase STRING
              Exclude  a  standard signature database (opt-out). This option can be used multiple
              Default: disabled

       DatabaseCustomURL STRING
              With this option you can provide custom sources for database files. This option can
              be used multiple times.  Support for:
                http(s)://, ftp(s)://, or file:// Example usage:
              Default: disabled

       HTTPProxyServer STR, HTTPProxyPort NUMBER
              Use  given  proxy  server and TCP port for database downloads.  The HTTPProxyServer
              may be prefixed with [scheme]:// to specify which kind of proxy is used.
                http://     HTTP Proxy. Default when no scheme or proxy type is specified.
                https://    HTTPS Proxy. (Added in 7.52.0 for OpenSSL, GnuTLS and NSS)
                socks4://   SOCKS4 Proxy.
                socks4a://  SOCKS4a Proxy. Proxy resolves URL hostname.
                socks5://   SOCKS5 Proxy.
                socks5h://  SOCKS5 Proxy. Proxy resolves URL hostname.

       HTTPProxyUsername STR,HTTPProxyPassword STRING
              Proxy usage is authenticated through given username and password.
              Default: disabled

       HTTPUserAgent STRING
              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.  As of
              ClamAV 0.103.3, this setting may not be used when updating from the  CDN
              and can only be used when updating from a private mirror.
              Default: clamav/version_number

       NotifyClamd STRING
              Notify a running clamd(8) to reload its database after a download has occurred. The
              path for clamd.conf file must be provided.
              Default: The default is to not notify clamd. See clamd.conf(5)'s  option  SelfCheck
              for how clamd(8) handles database updates in this case.

       OnUpdateExecute STRING
              Execute this command after the database has been successfully updated.
              Default: disabled

       OnErrorExecute STRING
              Execute this command after a database update has failed.
              Default: disabled

       OnOutdatedExecute STRING
              Execute this command when freshclam reports outdated version. In the command string
              %v will be replaced by the new version number.
              Default: disabled

       LocalIPAddress IP
              Use IP as client address for downloading databases. Useful for multi homed systems.
              Default: Use OS'es default outgoing IP address.

       ConnectTimeout NUMBER
              Timeout in seconds when connecting to database server.
              Default: 10

       ReceiveTimeout NUMBER
              Maximum time in seconds for each download operation. 0 means no timeout.
              Default: 0

       Bytecode BOOL
              This  option  enables  downloading  of  bytecode.cvd,  which  includes   additional
              detection mechanisms and improvements to the ClamAV engine.
              Default: yes
