What is antivirus-updater.exe?
antivirus-updater.exe is the updater component for Acme Antivirus. It runs in the background to check for new virus definitions and engine updates, downloads them securely, verifies integrity, and applies changes without user interaction.
The updater communicates over HTTPS to Acme servers to fetch signatures, engine files, and policy updates. It launches worker processes for downloads and applies updates while preserving active protection.
Quick Fact: Antivirus updaters typically run as background services to ensure protection remains current even when the UI is closed.
Types of Updater Processes
- Updater Service: Runs in background to manage updates
- Download Worker: Handles signature and engine file downloads
- Integrity Verifier: Checks file signatures and hashes
- Installer Helper: Applies updates to the engine
- Logger: Logs update activities and errors
