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 kilobytes. | ||
|
NUMBER |

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

SubmitDetectionStats STRING
When enabled freshclam will

be enabled in clamd.conf. The path for clamd.conf file must
be provided.
Default: disabled
DetectionStatsCountry STRING

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

location, please enable this option and enter a two-letter
code (see http://www.iana.org/domains/root/db/) of the
country of origin.
