NAME

       clamd.conf - Configuration file for Clam AntiVirus Daemon

DESCRIPTION

       clamd.conf configures the Clam AntiVirus daemon, clamd(8).

FILE FORMAT

       The  file  consists  of  comments and options with arguments. Each line
       that starts with a hash (#) symbol is a comment. Options and  arguments
       are  case  sensitive  and  of  the  form Option Argument. The (possibly
       optional) arguments are are of the following types:

       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.

DIRECTIVES

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

       Example

       StreamMaxLength SIZE
              Clamd  uses FTP-like protocol to receive data from remote
              clients. If you are using clamav-milter to  balance  load
              between  remote clamd daemons on firewall servers you may
              need to tune the Stream* options. This option allows  you
              to  specify  the  maximal  limit  for  data transfered to
              remote daemon when scanning  a  single  file.  It  should
              match your MTA’s limit for a maximal attachment size.
              Default: 10M

       StreamMinPort NUMBER
              Limit data port range.

              Limit data port range.
              Default: 2048

       DisableDefaultScanOptions
              By   default  clamd  uses  scan  options  recommended  by
              libclamav. This option disables recommended  options  and
              allows  you  to enable selected options. DO NOT ENABLE IT
              unless you know what you are doing.
              Default: disabled

       ScanPE PE stands for Portable Executable -  it’s  an  executable
              file  format  used  in  all  32-bit  versions  of Windows
              operating systems. This option allows ClamAV to perform a
              deeper   analysis  of  executable  files  and  it’s  also
              required for decompression of popular executable  packers
              such as UPX.
              Default: enabled

       DetectBrokenExecutables
              With   this  option  clamd  will  try  to  detect  broken
              executables and mark them as Broken.Executable.
              Default: disabled

              Enables scanning of Microsoft Office document macros.

              Default: enabled

       MailFollowURLs
              If an email contains URLs ClamAV can  download  and  scan
              them.  WARNING: This option may open your system to a DoS
              attack. Never use it on loaded servers.
              Default: disabled

       ScanArchive
              Enable archive scanning.
              Default: enabled

       ScanRAR
              Enable scanning of RAR archives. Due  to  license  issues
              libclamav does not support RAR 3.0 archives (only the old
              2.0 format  is  supported).  Because  some  users  report
              stability problems with unrarlib it’s disabled by default
              and must be enabled in the config file.
              Default: disabled

              Files  in  archives  larger  than  this  limit  won’t  be

              Default: 10M

       ArchiveMaxRecursion NUMBER
              Limit  archive  recursion  level. Value of 0 disables the

       ArchiveMaxFiles NUMBER
              Number of files to be scanned within archive. Value of  0
              disables the limit.
              Default: 1000

       ArchiveMaxCompressionRatio NUMBER
              Analyze compression ratio of every file in an archive and
              mark potential archive bombs as viruses (0  disables  the
              limit).
              Default: 250

       ArchiveLimitMemoryUsage
              Use   slower  decompression  algorithm  which  uses  less
              memory. This option affects bzip2 decompressor only.
              Default: disabled

       ArchiveBlockEncrypted
              Mark  encrypted  archives  as   viruses   (Encrypted.Zip,

              Mark   archives  as  viruses  (e.g  RAR.ExceededFileSize,
              Zip.ExceededFilesLimit)        if        ArchiveMaxFiles,
              ArchiveMaxFileSize,   or   ArchiveMaxRecursion  limit  is
              reached.
              Default: disabled
