  ----------------------------------------------------------------------
Usage:  Open a command prompt box and type: a2cmd

  Hint: You have to add the installation folder to the PATH system variable
  to be able to call a2cmd from any location in the dos prompt.

By default, the help dialog appears:
  ----------------------------------------------------------------------
a2cmd.exe [path] | [parameters]
  ----------------------------------------------------------------------
Scan types (can be combined) ------------

/f=[path], /files=[path]  
Scans specified disks, folders or files for malware infections. Folder paths must be enclosed in quotation marks. Multiple paths need to be delimited by commas. Example: a2cmd /f="c:\windows\","c:\program files\"

/quick    Scans all active programs, malware traces (registry, files) and Tracking Cookies.
/smart    Good and fast result, but only important folders will be scanned
/deep     Slowest scan. All files on all hard disks will be scanned deeply

/malware
Scans all places that Malware typically infects. A Malware Scan is the best choice for most users. It's fast and thoroughly examines the whole computer for any active Malware infections.

/rk                 Scans for active rootkits.
/m, /memory    Scans all active programs.
/t, /traces       Scans the registry and the file/folder structures on a hard disk for malware traces.

/c, /cookies
 Scans all cookies for Tracking Cookies. Supported browsers: MS Internet Explorer, Mozilla Firefox.

/fh=[handle], /pid=[PID]
 Scan a file by handle. Requires the ID of the process that keeps the handle.

/b=[pointer] /bs=[size] /pid=[PID]
 Scan a data buffer in memory. Requires the buffer size and the ID of the process that keeps the buffer.

Scan settings (for precise adjustment of the scan types) -----------

/pup
 Also detects Potentially Unwanted Programs (programs that are not specifically malicious but are often installed without user consent)

/h, /heuristic  Heuristic scan for unknown Malware
/r, /riskware   Alert Riskware that is often used by Malware
/a, /archive    Scans also within archive files such as ZIP, RAR, CAB, and self-extracting archives.
/n, /ntfs     Scans also hidden data flows in NTFS disks.
/ac, /advancedcaching      Uses the advanced caching to avoid unnecessary re-scans.

/dda, /directdiskaccess
 Scans with direct disk access mode which is slower. Not required when the rootkit scan is enabled.

/l=[path], /log=[path]
 Saves a scan log to the specified file. The text-based log is saved in Unicode format.
Example: a2cmd /malware /log="c:\scans\scan.log"

/la=[path], /logansi=[path]
 Same as the /l bzw /log parameter, but the log is saved in ANSI Format.

/x=[list], /ext=[list]     Scans only files with the specified extensions.
Example: a2cmd /f="c:\windows\" /x="exe, com, scr, bat"

/xe=[list], /extexclude=[list]
 Scans all files except those with the specified extensions.  Example: a2cmd /malware /xe="avi, bmp, mp3"

/wl=[path], /whitelist=[path]
 Uses the specified whitelist file for excluding certain files, folders or malware names in the scan. Whitelist files must be text files where each line is one of the items to be excluded.  Example: a2cmd /f="c:\" /wl="c:\whitelist.txt"

/d, /delete
 Deletes all detected malware objects at once during the scan. Also deletes references to the detected file, e.g. autorun entries in the registry.

/dq, /deletequick
 Deletes all detected malware objects at once during the scan. Only the detected file itself is deleted. Quicker than /d or /delete.

/q=[folder], /quarantine=[folder]
 Immediately place detected malware in quarantine during the scan. The quarantine folder can be specified. Detected objects are saved and encrypted there so that they cannot cause further damage.

/s, /service
 Defines if the Anti-Malware service is to be used for scanning.
 Background: When running many short scans, loading the scan engine afresh at each start of a2cmd is inefficient. Using the /s or /service parameter makes the Anti-Malware service load the engine and keep it loaded for later scans. If the service is not yet started or installed it is installed and started when the service parameter is run for the first time. This command is not available in Emsisoft Emergency Kit because the service component is not included.


Malware handling (to be used alone) ------------

/ql, /quarantinelist
 Lists all objects that are under quarantine. The consecutive number at the beginning of each line can be used for deleting or restoring (zero-based index).

/qr=[n], /quarantinerestore=[n]
 Restores an object under quarantine with the specified index number. If no number is specified, all objects are restored.
Example: a2cmd /qr=0

/qd=[n], /quarantinedelete=[n]    Deletes an object under quarantine with the specified index number.

Online updates (to be used alone)  -------

/u, /update
 Must be used alone. Runs an online update of all program components and signatures. If a2cmd is used as a part of Emsisoft Anti-Malware, this command triggers an update of the whole Emsisoft Anti-Malware package.

/ub, /updatebeta     Downloads the latest beta updates instead of stable updates.
/proxy=[proxyname:port]     Sets a proxy host and port number to be used for connections to the update server.
/proxyuser=[username]      Sets a proxy username if the proxy requires authentication.
/proxypassword=[password]     Sets a proxy password if the proxy requires authentication.

General commands  (to be used alone)

/?, /help   Shows an overview of all available parameters.
  ----------------------------------------------------------------------

  Example: a2cmd /f="c:\windows\" /m /t /c /h /r /a /n /q
  Description: Scans c:\windows. Memory, Traces and Cookie scan enabled.
               Uses heuristics, displays Riskware and scans in Archives and ADS.
               Puts found Malware in Quarantine.
