Scan installation packages. Option is enabled by default.

/AFS

Use forward slash to separate paths in an archive. Option is disabled by default.

Maximum size of a file inside an archive that is scanned (in KB). By default: unlimited.

/BI

Show information on virus databases. Option is enabled by default.

/CUSTOM

Perform a custom scan. If additional parameters are set (for example, objects to be scanned or /TM and /TB parameters), only the specified objects will be scanned. (For Scanner only.)

/CL

Use cloud checking. Option is enabled by default. (For Console Scanner only.)

Do not display estimated scan time. (For Console Scanner only.)

/DR

Scan folders recursively (scan subfolders). Option is enabled by default.

/E:<number_of_threads>

Perform scanning in specified number of threads.

/FAST

Perform an express scan of the system. If additional parameters are set (for example, objects to be scanned or /TM and /TB parameters), the specified objects will also be scanned. (For Scanner only.)

/FL:<file_name>

Scan paths listed in the specified file.

/FM:<mask>

Scan files matching the specified mask. By default, all files are scanned.

/FR:<regexpr>

Scan files matching the specified regular expression. By default, all files are scanned.

/FULL

Perform a full scan of all hard drives and removable media (including boot sectors). If additional parameters are set (for example, objects to be scanned or /TM and /TB parameters), an express scan will be performed, and the specified objects will be scanned. (For Scanner only.)

/FX:<mask>

Exclude from scan files that match the specified mask. (For Console Scanner only.)

/GO

Scanner operation mode that skips the questions that require answers from a user; decisions that require a selection are made automatically. This mode is useful for the automatic file scan; for example, for the daily or weekly hard disk scanning. An object for scanning must be indicated in the command line. Along with the /GO parameter, it is also possible to use the following parameters: /LITE, /FAST, /FULL. In this mode, the scanning stops when switching to the battery power.

/QL

Show the list of files quarantined on all disks. (For Console Scanner only.)

/QL:<logical_drive_letter>

Show the list of files quarantined on the specified logical drive. (For Console Scanner only.)

/QNA

Double quote paths.

/QR[:[d][:p]]

/QUIT

/QUIT—terminate Scanner once scanning is complete regardless of whether or not any actions have been applied to the detected threats. (For Scanner only.)

/RA:<file_name>

Action

Description

/AAD:<action>

action for adware (possible: DQIR)

/AAR:<action>

action for infected archives (possible: DQIR)

/ACN:<action>

action for infected installation packages (possible: DQIR)

/ADL:<action>

action for dialers (possible: DQIR)

/AHT:<action>

action for hacktools (possible: DQIR)

/AIC:<action>

/AIN:<action>

action for infected files (possible: CDQR)

/AJK:<action>

action for jokes (possible: DQIR)

/AML:<action>

action for infected mail files (possible: QIR)

/ARW:<action>

action for riskware (possible: DQIR)

/ASU:<action>

action for suspicious files (possible: DQIR)

Several switches can have modifiers that explicitly enable or disable options specified by these switches. For example, as follows:

/AC-

option is clearly disabled

/AC, /AC+

option is clearly enabled

These modifiers can be useful if the option was enabled or disabled by default or was set in the configuration file earlier. The following switches can have modifiers:

/AC, /AFS, /AR, /BI, /DR, /HA, /LN, /LS, /MA, /NB, /NT, /OK, /QNA, /REP, /SCC, /SCN, /SLS, /SPN, /SPS, /SST, /TB, /TM, /TR, /WCL.

For /FL parameter '-' modifier directs to scan the paths listed in the specified file and then delete this file.

For /ARC, /ARL, /ARS, /ART, /ARX, /NI[:X], /PAL, /RPC, /W parameters "0" value means that there is no limit.

The following example shows how to use command-line switches with Console Scanner:

[<path_to_program>]dwscancl /AR- /AIN:C /AIC:Q C:\

scan all files on disk 'C:', excluding those in archives; cure the infected files and move to quarantine those that cannot be cured. To run Scanner the same way, enter the dwscancl command name instead of dwscanner.
