## ## Example config file for the Clam AV daemon ## Please read the clamd.conf(5) manual before editing this file. ## # Comment or remove the line below. #Example # Uncomment this option to enable logging. # LogFile must be writable for the user running daemon. # A full path is required. # Default: disabled LogFile /var/log/clamav/clamd.log # By default the log file is locked for writing - the lock protects against # running clamd multiple times (if want to run another clamd, please # copy the configuration file, change the LogFile variable, and run # the daemon with --config-file option). # This option disables log file locking. # Default: no #LogFileUnlock yes # Maximum size of the log file. # Value of 0 disables the limit. # You may use 'M' or 'm' for megabytes (1M = 1m = 1048576 bytes) # and 'K' or 'k' for kilobytes (1K = 1k = 1024 bytes). To specify the size # in bytes just don't use modifiers. # Default: 1M LogFileMaxSize 2M # Log time with each message. # Default: no LogTime yes # Also log clean files. Useful in debugging but drastically increases the # log size. # Default: no #LogClean yes # Use system logger (can work together with LogFile). # Default: no LogSyslog yes # Specify the type of syslog messages - please refer to 'man syslog' # for facility names. # Default: LOG_LOCAL6 #LogFacility LOG_MAIL # Enable verbose logging. # Default: no LogVerbose yes # This option allows you to save a process identifier of the listening # daemon (main thread). # Default: disabled PidFile /var/run/clamav/clamd.pid # Optional path to the global temporary directory. # Default: system specific (usually /tmp or /var/tmp). #TemporaryDirectory /var/tmp # Path to the database directory. # Default: hardcoded (depends on installation options) #DatabaseDirectory /var/lib/clamav # The daemon can work in local mode, network mode or both. # Due to security reasons we recommend the local mode. # Path to a local socket file the daemon will listen on. # Default: disabled (must be specified by a user) LocalSocket /var/run/clamav/clamd.socket # Remove stale socket after unclean shutdown. # Default: yes #FixStaleSocket yes # TCP port address. # Default: no TCPSocket 3310 # TCP address. # By default we bind to INADDR_ANY, probably not wise. # Enable the following to provide some degree of protection # from the outside world. # Default: no #TCPAddr 127.0.0.1 # Maximum length the queue of pending connections may grow to. # Default: 15 #MaxConnectionQueueLength 30 # 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 options below. # Close the connection when the data size limit is exceeded. # The value should match your MTA's limit for a maximum attachment size. # Default: 25M #StreamMaxLength 10M # Limit port range. # Default: 1024 #StreamMinPort 30000 # Default: 2048 #StreamMaxPort 32000 # Maximum number of threads running at the same time. # Default: 10 #MaxThreads 20 # Waiting for data from a client socket will timeout after this time (seconds). # Value of 0 disables the timeout. # Default: 120 #ReadTimeout 300 # This option specifies the time (in seconds) after which clamd should # timeout if a client doesn't provide any initial command after connecting. # Default: 5 #CommandReadTimeout 5 # This option specifies how long to wait (in miliseconds) if the send buffer is full. # Keep this value low to prevent clamd hanging # # Default: 500 #SendBufTimeout 200 # Maximum number of queued items (including those being processed by MaxThreads threads) # It is recommended to have this value at least twice MaxThreads if possible. # WARNING: you shouldn't increase this too much to avoid running out of file descriptors, # the following condition should hold: # MaxThreads*MaxRecursion + (MaxQueue - MaxThreads) + 6< RLIMIT_NOFILE (usual max is 1024) # # Default: 100 #MaxQueue 200 # Waiting for a new job will timeout after this time (seconds). # Default: 30 #IdleTimeout 60 # Don't scan files and directories matching regex # This directive can be used multiple times # Default: scan all #ExcludePath ^/proc/ #ExcludePath ^/sys/ # Maximum depth directories are scanned at. # Default: 15 #MaxDirectoryRecursion 20 # Follow directory symlinks. # Default: no #FollowDirectorySymlinks yes # Follow regular file symlinks. # Default: no #FollowFileSymlinks yes # Perform a database check. # Default: 600 (10 min) #SelfCheck 600 # Execute a command when virus is found. In the command string %v will # be replaced with the virus name. # Default: no #VirusEvent /usr/local/bin/send_sms 123456789 "VIRUS ALERT: %v" # Run as another user (clamd must be started by root for this option to work) # Default: don't drop privileges #User clamav # Initialize supplementary group access (clamd must be started by root). # Default: no #AllowSupplementaryGroups no # Stop daemon when libclamav reports out of memory condition. #ExitOnOOM yes # Don't fork into background. # Default: no #Foreground yes # Enable debug messages in libclamav. # Default: no #Debug yes # Do not remove temporary files (for debug purposes). # Default: no #LeaveTemporaryFiles yes # Detect Possibly Unwanted Applications. # Default: no #DetectPUA yes # Exclude a specific PUA category. This directive can be used multiple times. # See http://www.clamav.net/support/pua for the complete list of PUA # categories. # Default: Load all categories (if DetectPUA is activated) #ExcludePUA NetTool #ExcludePUA PWTool # Only include a specific PUA category. This directive can be used multiple # times. # Default: Load all categories (if DetectPUA is activated) #IncludePUA Spy #IncludePUA Scanner #IncludePUA RAT # In some cases (eg. complex malware, exploits in graphic files, and others), # ClamAV uses special algorithms to provide accurate detection. This option # controls the algorithmic detection. # Default: yes #AlgorithmicDetection yes ## ## Executable files ## # PE stands for Portable Executable - it's an executable file format used # in all 32 and 64-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, FSG, # and Petite. # Default: yes #ScanPE yes # Executable and Linking Format is a standard format for UN*X executables. # This option allows you to control the scanning of ELF files. # Default: yes #ScanELF yes # With this option clamav will try to detect broken executables (both PE and # ELF) and mark them as Broken.Executable. # Default: no #DetectBrokenExecutables yes ## ## Documents ## # This option enables scanning of OLE2 files, such as Microsoft Office # documents and .msi files. # Default: yes #ScanOLE2 yes # This option enables scanning within PDF files. # Default: yes #ScanPDF yes ## ## Mail files ## # Enable internal e-mail scanner. # Default: yes ScanMail yes # 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: no #MailFollowURLs no # Scan RFC1341 messages split over many emails. # You will need to periodically clean up $TemporaryDirectory/clamav-partial directory. # WARNING: This option may open your system to a DoS attack. # Never use it on loaded servers. # Default: no #ScanPartialMessages yes # With this option enabled ClamAV will try to detect phishing attempts by using # signatures. # Default: yes #PhishingSignatures yes # Scan URLs found in mails for phishing attempts using heuristics. # Default: yes #PhishingScanURLs yes # Always block SSL mismatches in URLs, even if the URL isn't in the database. # This can lead to false positives. # # Default: no #PhishingAlwaysBlockSSLMismatch no # Always block cloaked URLs, even if URL isn't in database. # This can lead to false positives. # # Default: no #PhishingAlwaysBlockCloak no # Allow heuristic match to take precedence. # When enabled, if a heuristic scan (such as phishingScan) detects # a possible virus/phish it will stop scan immediately. Recommended, saves CPU # scan-time. # When disabled, virus/phish detected by heuristic scans will be reported only at # the end of a scan. If an archive contains both a heuristically detected # virus/phish, and a real malware, the real malware will be reported # # Keep this disabled if you intend to handle "*.Heuristics.*" viruses # differently from "real" malware. # If a non-heuristically-detected virus (signature-based) is found first, # the scan is interrupted immediately, regardless of this config option. # # Default: no #HeuristicScanPrecedence yes ## ## Data Loss Prevention (DLP) ## # Enable the DLP module # Default: No #StructuredDataDetection yes # This option sets the lowest number of Credit Card numbers found in a file # to generate a detect. # Default: 3 #StructuredMinCreditCardCount 5 # This option sets the lowest number of Social Security Numbers found # in a file to generate a detect. # Default: 3 #StructuredMinSSNCount 5 # With this option enabled the DLP module will search for valid # SSNs formatted as xxx-yy-zzzz # Default: yes #StructuredSSNFormatNormal yes # With this option enabled the DLP module will search for valid # SSNs formatted as xxxyyzzzz # Default: no #StructuredSSNFormatStripped yes ## ## HTML ## # Perform HTML normalisation and decryption of MS Script Encoder code. # Default: yes #ScanHTML yes ## ## Archives ## # ClamAV can scan within archives and compressed files. # Default: yes #ScanArchive yes # Mark encrypted archives as viruses (Encrypted.Zip, Encrypted.RAR). # Default: no #ArchiveBlockEncrypted no ## ## Limits ## # The options below protect your system against Denial of Service attacks # using archive bombs. # This option sets the maximum amount of data to be scanned for each input file. # Archives and other containers are recursively extracted and scanned up to this # value. # Value of 0 disables the limit # Note: disabling this limit or setting it too high may result in severe damage # to the system. # Default: 100M #MaxScanSize 150M # Files larger than this limit won't be scanned. Affects the input file itself # as well as files contained inside it (when the input file is an archive, a # document or some other kind of container). # Value of 0 disables the limit. # Note: disabling this limit or setting it too high may result in severe damage # to the system. # Default: 25M #MaxFileSize 30M # Nested archives are scanned recursively, e.g. if a Zip archive contains a RAR # file, all files within it will also be scanned. This options specifies how # deeply the process should be continued. # Note: disabling this limit or setting it too high may result in severe damage # to the system. # Value of 0 disables the limit. # Default: 16 #MaxRecursion 10 # Number of files to be scanned within an archive, a document, or any other # container file. # Value of 0 disables the limit. # Note: disabling this limit or setting it too high may result in severe damage # to the system. # Default: 10000 #MaxFiles 15000 ## ## Clamuko settings ## WARNING: This is experimental software. It is very likely it will hang ## up your system!!! ## # Enable Clamuko. Dazuko (/dev/dazuko) must be configured and running. # Default: no ClamukoScanOnAccess yes # Set access mask for Clamuko. # Default: no #ClamukoScanOnOpen yes #ClamukoScanOnClose yes #ClamukoScanOnExec yes # Set the include paths (all files inside them will be scanned). You can have # multiple ClamukoIncludePath directives but each directory must be added # in a seperate line. # Default: disabled #ClamukoIncludePath /home #ClamukoIncludePath /students # Set the exclude paths. All subdirectories are also excluded. # Default: disabled #ClamukoExcludePath /home/bofh # Don't scan files larger than ClamukoMaxFileSize # Value of 0 disables the limit. # Default: 5M #ClamukoMaxFileSize 10M
