avastui.exe

What is avastui.exe?

avastui.exe is the graphical user interface component for Avast Antivirus. It renders the protection dashboard, provides access to scans, shields configuration, licensing, notifications, and settings, and interacts with the core service AvastSvc.exe to display real-time status. It typically launches at startup and runs alongside the Avast protection stack.

AvastUI.exe is a Windows PE process that hosts the Avast control panel. It communicates with AvastSvc.exe via inter-process communication to display protection status, trigger user actions, and apply configuration changes. It does not perform core scanning itself but coordinates UI-driven tasks.

Why is it Running?

Reasons it's running:

• UI access and control: avastui.exe provides the main user interface for starting scans, viewing protection status, and adjusting shields and settings.
• IPC with core service: The UI communicates with AvastSvc.exe to fetch real-time protection data and mirror it on the dashboard.
• Status alerts and notifications: The UI surfaces alerts, scan results, and licensing information to the user through the Avast UI.
• Startup and session management: The UI initializes on login to present a ready dashboard and coordinates with AvastSvc.exe for ongoing protection tasks.
• Configuration changes: Changing settings in the Avast UI triggers updates to shields, scheduled scans, and other components via the core services.
