Emsisoft Commandline Scanner

For system administrators, security experts, and experienced commandline users. Check your system for malware infection with the Commandline Scanner. It includes all functions of the Anti-Malware scanner and both the top scan engines (Emsisoft Anti-Malware and Ikarus Antivirus).
The Commandline Scanner is a part of the Emsisoft Anti-Malware package, but it can also be downloaded as self-contained package on the download page.

Start

Open the Windows prompt (Start - Run - cmd.exe) and browse the folder that contains a2cmd.exe.

Example:
cd "c:\program files\Emsisoft Anti-Malware\"

Start the Commandline Scanner as follows:
a2cmd.exe

An overview of all available starting parameters is listed.

General parameters:

* /s, /service
Always has to be used in combination with a scan parameter. Defines if the Anti-Malware service is to be used for scanning.
Background: When running many short scans loading the scan engine new 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 gets installed and started when the service parameter is run for the first time.
* /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, only the update function of Emsisoft Anti-Malware should be used.
* /?, /help
Must be used alone. Shows an overview of all available parameters.
