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.

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
226 VirusEvent COMMAND
227 Execute a command when a virus is found. In the command string
228 %v will be replaced with the virus name. Additionally, two envi‐

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

324 saves CPU scan-time. When disabled, virus/phishing detected by
325 heuristic scans will be reported only at the end of a scan. If
326 an archive contains both a heuristically detected virus/phish‐
327 ing, and a real malware, the real malware will be reported. Keep
328 this disabled if you intend to handle "*.Heuristics.*" viruses
329 differently from "real" malware. If a non-heuristically-detected
330 virus (signature-based) is found first, the scan is interrupted
331 immediately, regardless of this config option.
332 Default: no
333
334 ScanPE BOOL
335 PE stands for Portable Executable - it's an executable file for‐
336 mat used in all 32 and 64-bit versions of Windows operating sys‐

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