What is mullvad-service.exe?

mullvad-service.exe is the background service for Mullvad VPN. It establishes and maintains the encrypted tunnel, handles DNS routing, and enforces the kill switch. You may see this process running even when the main UI is closed, as it keeps the VPN connection alive and ready to reconnect when needed.

This Windows service runs with elevated privileges to manage the VPN tunnel (WireGuard/OpenVPN), perform DNS redirection, and monitor connectivity, ensuring privacy and stability without constant UI prompts.

Quick Fact: Mullvad's service model keeps the VPN tunnel active in the background, so your IP remains hidden even when the app window is minimized or closed.

Types of Mullvad Service Components

Tunnel Process: Establishes and maintains the encrypted VPN tunnel using WireGuard
DNS Process: Routes DNS through Mullvad's DNS servers to prevent leaks
UI Helper Process: Communicates between the UI and background service
Kill Switch Monitor: Blocks all traffic if the VPN connection drops
Update Process: Handles software updates for the Mullvad client
Background Sync: synchronizes settings and account data with Mullvad servers

Is mullvad-service Safe?

Yes, mullvad-service.exe is safe when it's the legitimate file from Mullvad VPN downloaded from official sources (mullvad.net or official installers).

Is mullvad-service.exe a Virus or Malware?

The real mullvad-service.exe is NOT a virus. However, malware may mimic names to trick users.

How to Tell if mullvad-service.exe is Legitimate or Malware

File Location:: Must be in C:\Program Files\Mullvad VPN\ or C:\Program Files (x86)\Mullvad VPN\. Any mullvad-service.exe elsewhere is suspicious.
Digital Signature:: Right-click the file in Explorer → Properties → Digital Signatures. Should show "Mullvad VPN AB" as the signer.
Resource Usage:: Normal usage is 1-5% CPU and 40-160 MB memory when idle. Spikes during tunneling are normal; persistent high usage when idle is suspicious.
Behavior:: Should only run when Mullvad services are active; background activity without Mullvad UI is suspicious.

Red Flags: If mullvad-service.exe is located in unusual folders (Temp, AppData, System32), runs when Mullvad isn't installed, has no valid signature, or shows constant high resource use, scan with antivirus and reinstall Mullvad from mullvad.net. Beware of similarly-named files.

Why Is mullvad-service Running on My PC?
