 # Default: no
 #DisableCache 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. If you turn off this option, the original files will still be
 # scanned, but without additional processing.
 # Default: yes
 #ScanPE yes

 # Certain PE files contain an authenticode signature. By default, we check
 # the signature chain in the PE file against a database of trusted and
 # revoked certificates if the file being scanned is marked as a virus.
 # If any certificate in the chain validates against any trusted root, but
 # does not match any revoked certificate, the file is marked as whitelisted.
 # If the file does match a revoked certificate, the file is marked as virus.
 # The following setting completely turns off authenticode verification.
 # Default: no
 #DisableCertCheck yes

 # Executable and Linking Format is a standard format for UN*X executables.
 # This option allows you to control the scanning of ELF files.
 # If you turn off this option, the original files will still be scanned, but
 # without additional processing.
 # 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.
 # If you turn off this option, the original files will still be scanned, but
 # without additional processing.
 # 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.
 # If you turn off this option, the original files will still be scanned, but
 # without decoding and additional processing.
 # Default: yes
 #ScanPDF yes

 # This option enables scanning within SWF files.
 # If you turn off this option, the original files will still be scanned, but
 # without decoding and additional processing.

 # Enable internal e-mail scanner.
 # If you turn off this option, the original files will still be scanned, but
 # without parsing individual messages/attachments.
 # Default: yes
 #ScanMail yes

 # Scan RFC1341 messages split over many emails.
 # You will need to periodically clean up $TemporaryDirectory/clamav-partial directory.

 #	   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

 # Detect partition intersections in raw disk images using heuristics.
 # Default: no
 #PartitionIntersection 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

 # Mark encrypted archives as viruses (Encrypted.Zip, Encrypted.RAR).
 # Default: no
 #ArchiveBlockEncrypted no

 # Maximum size of a normalized HTML file to scan. HTML files larger than this
 # value after normalization will not be scanned.
 # Note: disabling this limit or setting it too high may result in severe damage
 # to the system.
 # Default: 2M

 # Maximum size of a script file to normalize. Script content larger than this
 # value will not be normalized or scanned.
 # Note: disabling this limit or setting it too high may result in severe damage
 # to the system.
 # Default: 5M
 #MaxScriptNormalize 5M

 # Maximum size of a ZIP file to reanalyze type recognition. ZIP files larger

	# the signature chain in the PE file against a database of trusted and
	# revoked certificates if the file being scanned is marked as a virus.
	# If any certificate in the chain validates against any trusted root, but
	# does not match any revoked certificate, the file is marked as whitelisted.
	# If the file does match a revoked certificate, the file is marked as virus.
	# The following setting completely turns off authenticode verification.
	# Default: no
	#DisableCertCheck yes

	# Executable and Linking Format is a standard format for UN*X executables.
	# This option allows you to control the scanning of ELF files.
	# If you turn off this option, the original files will still be scanned, but

	# Default: yes
	#ScanELF yes

	# With this option clamav will try to detect broken executables (both PE and
	# ELF) and mark them as Broken.Executable.

	# This option enables scanning of OLE2 files, such as Microsoft Office

	# without additional processing.
	# 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".

	# This option enables scanning within PDF files.
	# If you turn off this option, the original files will still be scanned, but
	# without decoding and additional processing.

	# Always block cloaked URLs, even if URL isn't in database.
	# This can lead to false positives.
	#
	# Default: no
	#PhishingAlwaysBlockCloak no

	# Detect partition intersections in raw disk images using heuristics.
	# Default: no
	#PartitionIntersection 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
