Quick Answer
protonvpn-helper.exe is safe. It's ProtonVPN's official helper process that coordinates tunnels, server selection, DNS protection, and background connectivity.
What is protonvpn-helper.exe?
protonvpn-helper.exe is the background service for the ProtonVPN client that coordinates VPN tunnels, server selection, and network integration on Windows. It starts with the app, maintains the active connection, and handles status updates, diagnostics, and automatic reconnect attempts.
ProtonVPN Helper runs as a low-privilege process to establish and manage VPN tunnels via WireGuard/OpenVPN, coordinating routing, DNS leakage protection, and automatic reconnect logic without exposing user credentials. It communicates with the main app through interprocess messages.
Quick Fact: ProtonVPN Helper manages tunnel control and DNS leakage protection in the background, enabling seamless server switching without disrupting your apps.

Is protonvpn-helper.exe a Virus or Malware?
The real protonvpn-helper.exe is NOT a virus. Malware may masquerade as it. Always verify digital signature and path.
How to Tell if protonvpn-helper.exe is Legitimate or Malware
- File Location:: Must be in C:\Program Files\ProtonVPN\ or C:\Program Files (x86)\ProtonVPN\, with protonvpn-helper.exe present.
- Digital Signature:: Right-click the process in Task Manager → Open file location → Right-click protonvpn-helper.exe → Properties → Digital Signatures. Should show "Proton AG" as signer.
- Resource Usage:: Normal usage is 1-8% CPU and 50-180 MB total memory; consistently high usage when idle is suspicious.
- Behavior:: The process should align with ProtonVPN app activity; persistent background operation without the app running may indicate malware.
Red Flags: If protonvpn-helper.exe is located in unusual folders (like Temp or AppData) or has no valid signature, or runs when the ProtonVPN client is closed, scan with a reputable antivirus. Beware of similarly-named files.

protonvpn-helper.exe runs when you start the ProtonVPN client or when the VPN is configured to run in background mode. It maintains tunnels and ensures rapid reconnects when the network changes.
Reasons it's running:
- Active VPN Session: Maintains the current tunnel and data routing for your active ProtonVPN connection.
- Background DNS Protection: Manages DNS settings to prevent leaks and protect privacy even when apps query domains.
- Auto-Reconnect and Failover: Continuously monitors connectivity and automatically reconnects if the tunnel drops.
- Startup and Tray Integration: Runs at startup or as a system tray helper to show status and quick actions.
- Application Updates: Updates or validates ProtonVPN components in the background to keep security features enabled.
Can I Disable or Remove protonvpn-helper.exe?
Yes, you can disable protonvpn-helper.exe. It's safe to close ProtonVPN and disable background activity if you don't use the service.
