## ## 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/copfilter/default/opt/clamav/var/log/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 15M # Log time with each message. # Default: no LogTime yes # Also log clean files.

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 # With this option enabled OLE2 files with VBA macros, which were not # detected by signatures will be marked as "Heuristics.OLE2.ContainsMacros". # Default: no #OLE2BlockMacros no # This option enables scanning within PDF files. # Default: no 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. # (available in experimental builds only) # 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. # (available in experimental builds only) # # 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.

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 # With this option enabled ClamAV will load bytecode from the database. # It is highly recommended you keep this option on, otherwise you'll miss detections for many new viruses. # Default: yes Bytecode yes # Set bytecode security level. # Possible values: # None - no security at all, meant for debugging. DO NOT USE THIS ON PRODUCTION SYSTEMS # This value is only available if clamav was built with --enable-debug! # TrustSigned - trust bytecode loaded from signed .c[lv]d files, # insert runtime safety checks for bytecode loaded from other sources # Paranoid - don't trust any bytecode, insert runtime checks for all # Recommended: TrustSigned, because bytecode in .cvd files already has these checks # Note that by default only signed bytecode is loaded, currently you can only # load unsigned bytecode in --enable-debug mode. # # Default: TrustSigned # BytecodeSecurity TrustSigned # Set bytecode timeout in miliseconds. # # Default: 5000 # BytecodeTimeout 1000
