Dr.Web Enterprise Security Suite 12.0 updated

April 14, 2021

Russian anti-virus company Doctor Web has updated the server software, as well as a number of agent components, in Dr.Web Enterprise Security Suite 12.0. The updated components include Dr.Web Updater (, Lua-script for updater (, Dr.Web Enterprise Agent for Windows setup (, Dr.Web Enterprise Agent ( and Dr.Web Enterprise Agent (AD Setup) (12.04.02250). Furthermore, the new modules Lua-script for meta ( and ES Update Helper ( have been introduced. The update delivers fixes for identified issues and ensures that Dr.Web software cannot be installed on Windows machines that do not support SHA-256.

If no SHA-256 support is available on a PC with an existing agent software installation, the updated Control Center now displays a message prompting the user to install the required operating system updates. Updates from the comps group are now blocked. Only the virus databases will continue to receive updates. Dr.Web can no longer be installed on Windows PCs that lack SHA-256 support. A message is displayed to inform the user that the corresponding Windows updates must be installed.

Important: to ensure that the Dr.Web software operates correctly under Windows Vista, Windows 7, Windows Server 2008 or Windows Server 2008 R2, Microsoft security updates providing SHA-256 support must be installed in these systems. For additional information, please refer to this guide:

  • Also resolved was an issue causing an incorrect number of active hosts running Windows 10 to be displayed in the anti-virus network view;
