What is avastsvc.exe?

avastsvc.exe is Avast Antivirus Service, a Windows background process that hosts the core protection engine for Avast. It coordinates real-time shields, file and web scanning, updates virus definitions, and maintains protection while you work. Because it runs continuously, you may notice it consume CPU or memory during scans or updates.

The AvastSvc.exe process runs as a Windows service (Avast Antivirus Service) under SYSTEM-like credentials and orchestrates Avast components. It launches protection modules, handles scheduled and on-demand scans, update tasks, and exposes protection status to the Avast UI.
