DIRECTIVES

       When an option is not used (hashed or doesn't exist in the configuration file) freshclam takes a default action.

       Example
	      If this option is set freshclam will not run.

       DatabaseMirror STRING
	      Server name where database updates are downloaded from. In order to download the database from the closest mirror you should config-
	      ure 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

	      Default: enabled

       CompressLocalDatabase BOOL
	      By  default  freshclam  will  keep  the  local databases (.cld) uncompressed to make their handling faster. With this option you can

	      ferent User-Agent header.
	      Default: clamav/version_number

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

       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: 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  Cla-
	      mAV 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. 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 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.
	      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 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 fresh-
	      clam starts submitting information to our stats collecting service, you will be able to view the statistics of this clamd  installa-
	      tion  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.
	      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 in-
	      frastructure to distribute the database and its updates but all  the  contents  are  provided  under  Google's  terms  of  use.  See
	      http://code.google.com/support/bin/answer.py?answer=70015 and http://safebrowsing.clamav.net 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
