Quick Answer
log-viewer-launcher.exe is safe. It is the launcher component for the LogView log viewer, coordinating opening, indexing, and rendering of log files.
What is log-viewer-launcher.exe?
log-viewer-launcher.exe is the coordinator for the LogView log viewing suite. It initiates the log viewer, loads recent log files, applies active filters, and manages background tasks such as indexing and updates to ensure responsive log exploration.
This executable acts as a thin orchestrator that launches the main log-viewer UI, handles task orchestration, and offloads heavy work to dedicated viewer/indexer processes to keep the UI responsive.
Quick Fact: The launcher design separates UI from heavy log indexing to improve responsiveness during large log loads.
Types of LogView Processes
- Launcher Process: Main process coordinating log-opening actions.
- Viewer Process: Renders and displays log content opened by the launcher.
- Indexer Process: Parses and indexes log entries for fast search.
- Updater Process: Checks for updates to the launcher and viewer components.
- Filter/Search Helper: Manages search queries and active filtering rules.
- Background Cleaner: Performs cleanup like temporary files and session tidy-up.
Is log-viewer-launcher.exe Safe?
Yes, log-viewer-launcher.exe is safe when it is the legitimate file from LogView Technologies downloaded from official sources or bundled with LogView installations.
Is log-viewer-launcher.exe a Virus or Malware?
The real log-viewer-launcher.exe is NOT a virus. However, malware sometimes disguises itself with similar names to deceive users.
How to Tell if log-viewer-launcher.exe is Legitimate or Malware
- File Location: Must be in C:\Program Files\LogView\Launcher\log-viewer-launcher.exe or C:\Program Files (x86)\LogView\Launcher\log-viewer-launcher.exe. Any other path is suspicious.
- Digital Signature: Right-click log-viewer-launcher.exe -> Properties -> Digital Signatures. Should show 'LogView Technologies' as the signer.
- Resource Usage: Normal usage is 1-8% CPU and 30-120 MB memory during idle or indexing. Constant high usage without activity is suspicious.
