NAME
       clamscan - scan files and directories for viruses

SYNOPSIS
       clamscan [options] [file/directory/-]

DESCRIPTION
       clamscan is a command line anti-virus scanner.

OPTIONS
       Most  of	 the  options are simple switches which enable or disable some
       features. Options marked with [=yes/no(*)] can be  optionally  followed
       by  =yes/=no; if they get called without the boolean argument the scan‐
       ner will assume 'yes'. The asterisk marks the default internal  setting
       for a given option.

       -h, --help
	      Print help information and exit.

       -V, --version
	      Print version number and exit.

       -v, --verbose
	      Be verbose.

       --debug
	      Display debug messages from libclamav.

       --quiet
	      Be quiet (only print error messages).

       --stdout
	      Write all messages (except for libclamav output) to the standard
	      output (stdout).

       -d FILE/DIR, --database=FILE/DIR
	      Load virus database from FILE or load all virus  database	 files
	      from DIR.

       --official-db-only=[yes/no(*)]
	      Only  load  the  official	 signatures  published	by  the ClamAV
	      project.

       -l FILE, --log=FILE
	      Save scan report to FILE.

       --tempdir=DIRECTORY
	      Create temporary files in DIRECTORY. Directory must be  writable
	      for the '' user or unprivileged user running clamscan.

       --leave-temps
	      Do not remove temporary files.

       -f FILE, --file-list=FILE
	      Scan files listed line by line in FILE.

       -r, --recursive
	      Scan  directories	 recursively.  All  the	 subdirectories in the
	      given directory will be scanned.

       --cross-fs=[yes(*)/no]
	      Scan files and directories on other filesystems.

       --bell Sound bell on virus detection.

       --no-summary
	      Do not display summary at the end of scanning.

       --exclude=REGEX, --exclude-dir=REGEX
	      Don't scan file/directory	 names	matching  regular  expression.
	      These options can be used multiple times.

       --include=REGEX, --include-dir=REGEX
	      Only  scan  file/directory  matching  regular  expression. These
	      options can be used multiple times.

       -i, --infected
	      Only print infected files.

       --remove[=yes/no(*)]
	      Remove infected files. Be careful.

       --move=DIRECTORY
	      Move infected files into DIRECTORY. Directory must  be  writable
	      for the '' user or unprivileged user running clamscan.

       --copy=DIRECTORY
	      Copy  infected  files into DIRECTORY. Directory must be writable
	      for the '' user or unprivileged user running clamscan.

       --bytecode[=yes(*)/no]
	      With this option enabled ClamAV  will  load  bytecode  from  the
	      database.	 It  is highly recommended you keep this option turned
	      on, otherwise you may miss detections for many new viruses.

       --bytecode-trust-all[=yes/no(*)]
	      This option disables safety checks and makes  ClamAV  trust  all
	      bytecode. It should only be used for debugging.

       --bytecode-timeout=N
	      Set bytecode timeout in milliseconds (default: 60000 = 60s)

       --detect-pua[=yes/no(*)]
	      Detect Possibly Unwanted Applications.

       --exclude-pua=CATEGORY
	      Exclude  a specific PUA category. This option can be used multi‐
	      ple times. See http://www.clamav.net/support/pua	for  the  com‐
	      plete list of PUA

       --include-pua=CATEGORY
	      Only  include  a	specific PUA category. This option can be used
	      multiple times. See  http://www.clamav.net/support/pua  for  the
	      complete list of PUA

       --detect-structured[=yes/no(*)]
	      Use  the	DLP  (Data  Loss  Prevention) module to detect SSN and
	      Credit Card numbers inside documents/text files.

       --structured-ssn-format=X
	      X=0: search for valid SSNs formatted  as	xxx-yy-zzzz  (normal);
	      X=1:  search  for	 valid SSNs formatted as xxxyyzzzz (stripped);
	      X=2: search for both formats. Default is 0.

       --structured-ssn-count=#n
	      This option sets the lowest number of  Social  Security  Numbers
	      found in a file to generate a detect (default: 3).

       --structured-cc-count=#n
	      This  option sets the lowest number of Credit Card numbers found
	      in a file to generate a detect (default: 3).

       --scan-mail[=yes(*)/no]
	      Scan mail files.

       --phishing-sigs[=yes(*)/no]
	      Use the signature-based phishing detection.

       --phishing-scan-urls[=yes(*)/no]
	      Use the url-based heuristic phishing detection (Phishing.Heuris‐
	      tics.Email.*)

       --heuristic-scan-precedence[=yes/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 (signa‐
	      ture-based) is found first,  the	scan  is  interrupted  immedi‐
	      ately, regardless of this config option.

       --phishing-ssl[=yes/no(*)]
	      Block SSL mismatches in URLs (might lead to false positives!).

       --phishing-cloak[=yes/no(*)]
	      Block cloaked URLs (might lead to some false positives).

       --algorithmic-detection[=yes(*)/no]
	      In  some	cases (eg. complex malware, exploits in graphic files,
	      and others), ClamAV uses special algorithms to provide  accurate
	      detection.  This	option	can be used to control the algorithmic
	      detection.

       --scan-pe[=yes(*)/no]
	      PE stands for Portable Executable - it's an executable file for‐
	      mat used in all 32-bit versions of Windows operating systems. By
	      default ClamAV performs deeper analysis of executable files  and
	      attempts	to  decompress popular executable packers such as UPX,
	      Petite, and FSG.

       --scan-elf[=yes(*)/no]
	      Executable and Linking Format is a standard format for UN*X exe‐
	      cutables. This option controls the ELF support.

       --scan-ole2[=yes(*)/no]
	      Scan Microsoft Office documents and .msi files.

       --scan-pdf[=yes(*)/no]
	      Scan within PDF files.

       --scan-html[=yes(*)/no]
	      Detect,  normalize/decrypt  and  scan  HTML  files  and embedded
	      scripts.

       --scan-archive[=yes(*)/no]
	      Scan archives supported by libclamav.

       --detect-broken[=yes/no(*)]
	      Mark broken executables as viruses (Broken.Executable).

       --block-encrypted[=yes/no(*)]
	      Mark   encrypted	  archives    as    viruses    (Encrypted.Zip,
	      Encrypted.RAR).

       --max-files=#n
	      Extract at most #n files from each scanned file (when this is an
	      archive, a document or another kind of container).  This	option
	      protects your system against DoS attacks (default: 10000)

       --max-filesize=#n
	      Extract and scan at most #n kilobytes from each archive. You may
	      pass the value in megabytes in format xM or xm,  where  x	 is  a
	      number.  This  option  protects  your system against DoS attacks
	      (default: 25 MB, max: <4 GB)

       --max-scansize=#n
	      Extract and scan at most #n kilobytes from  each	scanned	 file.
	      You  may pass the value in megabytes in format xM or xm, where x
	      is a number.  This  option  protects  your  system  against  DoS
	      attacks (default: 100 MB, max: <4 GB)

       --max-recursion=#n
	      Set  archive  recursion  level  limit. This option protects your
	      system against DoS attacks (default: 16).

       --max-dir-recursion=#n
	      Maximum depth directories are scanned at (default: 15).

EXAMPLES
       (0) Scan a single file:

	      clamscan file

       (1) Scan a current working directory:

	      clamscan

       (2) Scan all files (and subdirectories) in /home:

	      clamscan -r /home

       (3) Load database from a file:

	      clamscan -d /tmp/newclamdb -r /tmp

       (4) Scan a data stream:

	      cat testfile | clamscan -

       (5) Scan a mail spool directory:

	      clamscan -r /var/spool/mail

RETURN CODES
       0 : No virus found.

       1 : Virus(es) found.

       2 : Some error(s) occured.
