       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

              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

              Default: no

       AllowSupplementaryGroups BOOL
              Initialize supplementary group access (freshclam must be started by root).
              Default: disabled

       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 two entries: (or for IPv6) and
      (in this order). Please replace XY with your country code (see
      is  a  round-robin
              record  which points to our most reliable mirrors. It's used as a fall back in case
     is not working.

       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)

              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. Here you can find a list of
              available databases:
              Default: disabled

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

       HTTPProxyServer STR, HTTPProxyPort NUMBER
              Use  given proxy server and TCP port for database downloads. HTTPProxyPort defaults
              to 8080.

       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.
              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

              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
              Timeout in seconds when reading from database server.
              Default: 30

       SubmitDetectionStats STRING
              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. Freshclam will connect to clamd in order to get
              the recent statistics. The path for clamd.conf file must be provided.
              Default: disabled

       DetectionStatsCountry STRING
              Country of origin of malware/detection statistics (for statistical purposes  only).
              The  statistics  collector  at 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
     of the country of origin.
              Default: disabled

       DetectionStatsHostID STRING
              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
     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
     with the same credentials  you  used  to  generate  the
              HostID.  For  more  information  refer  to:
              cctts/. This feature requires SubmitDetectionStats to be enabled.
              Default: disabled

       SafeBrowsing BOOL
              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 provided under Google's terms of use. See
     for more information.
              Default: disabled

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