How it works

The Emsisoft Emergency Kit contains a collection of programs that can be used without software installation to scan for malware and clean infected computers.

Emsisoft Emergency Kit Scanner

The Emsisoft Emergency Kit Scanner includes the powerful Emsisoft Scanner complete with graphical user interface. Scan infected Windows devices for viruses, ransomware, backdoor trojans, bots, and other malicious programs.

Emsisoft Commandline Scanner

This scanner contains the same functionality as the Emergency Kit Scanner but without a graphical user interface. The command line tool is made for professionals and is optimized for automated jobs.

To run the Emsisoft Commandline Scanner, perform the following actions:

– Open a command prompt window (Run: cmd.exe)
– Switch to the folder of the executable files (e.g.: cd c:\EEK\bin64)
– Run the scanner without args: a2cmd.exe

Next you will see a help page describing all available run arguments.

The following parameter is an example of scanning drive c:\ with Memory, Traces (Registry) scan enabled, and archive support active. Detected Malware is moved to quarantine.

a2cmd.exe /f="c:\" /m /t /a /q="c:\quarantine\"

Check our complete list of supported run arguments.
