12 The file consists of comments and options with arguments. Each line
13 which starts with a hash (#) symbol is ignored by the parser. Options
14 and arguments are case sensitive and of the form Option Argument. The
15 arguments are of the following types:
16
17 BOOL Boolean value (yes/no or true/false or 1/0).
18
19 STRING String without blank characters.
20
21 SIZE Size in bytes. You can use 'M' or 'm' modifiers for megabytes
22 and 'K' or 'k' for kilobytes. To specify the size in bytes just
23 don't use modifiers.

215 ConcurrentDatabaseReload BOOL
216 Enable non-blocking (multi-threaded/concurrent) database
217 reloads. This feature will temporarily load a second scanning
218 engine while scanning continues using the first engine. Once
219 loaded, the new engine takes over. The old engine is removed as
220 soon as all scans using the old engine have completed. This fea‐
221 ture requires more RAM, so this option is provided in case users
222 are willing to block scans during reload in exchange for lower
223 RAM requirements.
224 Default: yes
225

319 detection. This option controls the algorithmic detection.
320 Default: yes
321
322 HeuristicScanPrecedence BOOL
323 Allow heuristic match to take precedence. When enabled, if a
324 heuristic scan (such as phishingScan) detects a possible

326 saves CPU scan-time. When disabled, virus/phishing detected by
327 heuristic scans will be reported only at the end of a scan. If
328 an archive contains both a heuristically detected virus/phish‐
329 ing, and a real malware, the real malware will be reported. Keep
330 this disabled if you intend to handle "*.Heuristics.*" viruses
331 differently from "real" malware. If a non-heuristically-detected
332 virus (signature-based) is found first, the scan is interrupted
333 immediately, regardless of this config option.
334 Default: no
335
336 ScanPE BOOL

666 With this option you can whitelist the root UID (0). Processes
667 run under root will be able to access all files without trigger‐
668 ing scans or permission denied events.
669 Note that if clamd cannot check the uid of the process that gen‐
670 erated an on-access scan event (e.g., because OnAccessPrevention
671 was not enabled, and the process already exited), clamd will
672 perform a scan. Thus, setting OnAccessExcludeRootUID is not
673 guaranteed to prevent every access by the root user from trig‐
674 gering a scan (unless OnAccessPrevention is enabled).
675 Default: no
676
677 OnAccessExcludeUID NUMBER
678 With this option you can whitelist specific UIDs. Processes with
679 these UIDs will be able to access all files without triggering
680 scans or permission denied events.
681 This option can be used multiple times (one per line).
682 Note: using a value of 0 on any line will disable this option
683 entirely. To whitelist the root UID (0) please enable the OnAc‐
684 cessExcludeRootUID option.
685 Also note that if clamd cannot check the uid of the process that
686 generated an on-access scan event (e.g., because OnAccessPreven‐
687 tion was not enabled, and the process already exited), clamd
688 will perform a scan. Thus, setting OnAccessExcludeUID is not
689 guaranteed to prevent every access by the specified uid from
690 triggering a scan (unless OnAccessPrevention is enabled).
691 Default: disabled
692
693 OnAccessExcludeUname STRING
694 This option allows exclusions via user names when using the on-
695 access scanning client. It can be used multiple times, and has
696 the same potential race condition limitations of the OnAccessEx‐
697 cludeUID option.
698 Default: disabled
699
700 OnAccessMaxFileSize SIZE
701 Files larger than this value will not be scanned in on access.
702 Default: 5M
703
704 OnAccessMaxThreads NUMBER
705 Max number of scanning threads to allocate to the OnAccess
706 thread pool at startup. These threads are the ones responsible
707 for creating a connection with the daemon and kicking off scan‐
708 ning after an event has been processed. To prevent clamonacc
709 from consuming all clamd's resources keep this lower than
710 clamd's max threads.
711 Default: 5
712
713 OnAccessCurlTimeout NUMBER
714 Max amount of time (in milliseconds) that the OnAccess client
715 should spend for every connect, send, and recieve attempt when
716 communicating with clamd via curl.
717 Default: 5000 (5 seconds)
718
719 OnAccessMountPath STRING
720 Specifies a mount point (including all files and directories
721 under it), which should be scanned on access. This option can be
722 used multiple times.
723 Default: disabled
724
725 OnAccessDisableDDD BOOL
726 Disables the dynamic directory determination system which allows
727 for recursively watching include paths.
728 Default: no
729
730 OnAccessPrevention BOOL
731 Enables fanotify blocking when malicious files are found.
732 Default: disabled
733
734 OnAccessRetryAttempts NUMBER
735 Number of times the OnAccess client will retry a failed scan due
736 to connection problems (or other issues).
737 Default: 0
738
739 OnAccessDenyOnError BOOL
740 When using prevention, if this option is turned on, any errors
741 that occur during scanning will result in the event attempt
742 being denied. This could potentially lead to unwanted system be‐
743 haviour with certain configurations, so the client defaults this
744 to off and prefers allowing access events in case of scan or
745 connection error.
746 Default: no
747
748 OnAccessExtraScanning BOOL
749 Toggles extra scanning and notifications when a file or direc‐
750 tory is created or moved.
751 Requires the DDD system to kick-off extra scans.
752 Default: no
753
754 DisableCertCheck BOOL
755 Disable authenticode certificate chain verification in PE files.
756 Default: no
757
759 All options expressing a size are limited to max 4GB. Values in excess
760 will be reset to the maximum.
