The component is designed to refer to the Dr.Web Cloud service to scan contents of the specified file for threats unknown to the local Dr.Web Scanning Engine), and to check whether the specified URL belongs to any of Doctor Web’s predefined categories of web resources.

Dr.Web CloudD is automatically run by the configuration daemon. The component is run upon receiving a command from the user or one of the Dr.Web for UNIX components. The operation scheme is shown in the figure below.

Figure 1. Diagram of the components’ operation

Requests to the Dr.Web Cloud service (to perform scanning of URL and files) via this component can send various components of Dr.Web for UNIX, marked in the scheme as “Other component” (depending on the product).

Besides that, the component is used during the scanning of files on the command from  the Dr.Web Ctl command-line-based management tool for Dr.Web for UNIX (accessed via drweb-ctl command): upon detection of threats, Dr.Web Scanning Engine sends file report to Dr.Web Cloud. A user can perform manual scanning of files and URLs he is interested in, search for information in Dr.Web Cloud using the corresponding tool commands (cloudscan and cloudcheck respectively).
