What is drweb.exe?
drweb.exe is the main executable for Doctor Web's antivirus suite on Windows. It coordinates protection activities and communicates with update and scanning components, often spawning multiple drweb-related processes as protection modules operate in tandem.
Dr.Web employs a multi-process architecture: the drweb.exe engine coordinates scanning, while dedicated services handle real-time checks, updates, and reporting. These processes run with user-mode privileges and may start as Windows services.
Quick Fact: Dr.Web's protection model uses modular processes to isolate scanning, updates, and UI for stability and security.
