What is termius.exe?

termius.exe is the main executable for Termius Desktop, the cross‑platform SSH client. It launches the graphical interface, manages SSH sessions, hosts, and credentials, and coordinates secure tunnels with cloud sync. Depending on your configuration, multiple worker processes may run to handle individual sessions.

Termius Desktop uses an Electron/Node.js base; each connection can spawn a separate renderer for a session, and a background agent handles SSH keys and cloud sync. This architecture improves responsiveness and isolation between tasks.

Quick Fact: Termius Desktop leverages Electron for a consistent UI across Windows, macOS, and Linux, with session isolation to improve stability.

Types of Termius Processes

Main UI Process: User interface and menu handling (1 instance)
Renderer Process: Each active SSH session or tab (multiple instances)
SSH Agent / Key Manager: Handles keys and authentication for sessions
Cloud Sync/Background: Synchronizes hosts, credentials, and settings with the cloud
Utility/Background Tasks: Notifications, session restoration, and network checks

Is termius.exe Safe?

Yes, termius.exe is safe when it's the legitimate file from Termius downloaded from official sources (termius.com or the Microsoft Store for the app).

Is termius.exe a Virus or Malware?

The real termius.exe is NOT a virus. However, malware may masquerade with similar file names.

How to Tell if termius.exe is Legitimate or Malware

File Location: Must be in C:\\Program Files\\Termius\\termius.exe or C:\\Program Files (x86)\\Termius\\termius.exe. Any other location is suspicious.
Digital Signature: Right-click the file in Explorer -> Properties -> Digital Signatures. Should show a valid signature from "Termius LLC" or the official signer.
Resource Usage: Normal usage is 2-15% CPU per session, 60-320 MB total memory. Constant high usage when the app is not running is suspicious.
Behavior: Termius should only run when you launch the app. Multiple background processes with no UI could indicate hijacking.

Red Flags: If termius.exe is located in unusual folders (like Temp, AppData\\Roaming, or System32), runs when the app isn't open, has no valid signature, or uses excessive resources constantly, run a full antivirus scan. Beware of similarly-named files like "termius.exe" from untrusted sources.

Why Is termius.exe Running on My PC?

termius.exe runs when you start Termius Desktop or when background sync, SSH agent, or session restoration tasks are active.

Reasons it's running:

Active User Interaction: You are actively using Termius; each open session or tab may launch a separate process for responsiveness.
Background Cloud Sync: Termius syncs hosts, credentials, and settings to the cloud to enable cross-device access.
Startup Launch: Termius is configured to run at Windows startup or on system login.
SSH Agent/Keyring: An internal agent maintains SSH keys and authentication for quick connections.
Session Restoration & Notifications: Background tasks restore previous sessions and deliver connection alerts.

Can I Disable or Remove termius.exe?

Yes, you can disable termius.exe. It's safe to close Termius when not in use, and you can uninstall it completely if you no longer need the SSH client.

How to Stop termius.exe

End Individual Sessions: In Termius, close individual sessions or disconnect SSH sessions to reduce resource usage.
Close Desktop App: Quit the Termius desktop app via the File menu or the window close button.
End All Processes: Open Windows Task Manager (Ctrl+Shift+Esc), locate termius.exe, right-click -> End Task
Prevent Startup: Task Manager -> Startup tab -> Disable Termius
Pause Background Sync: Termius Settings -> Sync -> Turn off cloud sync or schedule downtime

How to Uninstall Termius

✔ Windows Settings → Apps → Apps & Features → Termius → Uninstall
✔ Control Panel → Programs → Uninstall a program → Termius → Uninstall
✔ Consider alternative SSH clients: PuTTY, OpenSSH, or other cross-platform tools

Common Problems: High CPU or Memory Usage

If termius.exe is consuming excessive resources:

Common Causes & Solutions

Too many active SSH sessions: Close unused sessions or use the session manager to suspend idle connections.
Background cloud sync: Disable or limit sync frequency in Settings → Sync.
Large key caches or saved credentials: Reduce stored keys or clear cached credentials in Settings → Security.
Outdated Termius version: Update Termius to the latest version via Help → Check for updates.
Malicious extensions or plugins: Disable any third-party plugins and verify extension sources.
Renderer process overload: Restart Termius or reduce the number of concurrent SSH connections.

Quick Fixes:
1. Open Termius Task Manager or use the app's session manager to identify high-usage sessions
2. Close unused sessions and connections
3. Update Termius to the latest version
4. Disable or limit cloud sync
5. Restart Termius if anomalies persist

Frequently Asked Questions

Is termius.exe a virus?

No, the legitimate termius.exe from Termius is not a virus. Verify the file is located in C:\\Program Files\\Termius\\termius.exe and has a valid digital signature from "Termius LLC". Malware sometimes uses similar names to disguise itself.

Why is termius.exe using so much CPU?

High CPU is typically caused by numerous active SSH sessions or cloud sync operations. Use Termius Task Manager (or Windows Task Manager) to identify the culprit, then close the problematic session, adjust sync, or update Termius.

Can I delete termius.exe?

Yes, you can uninstall Termius from Windows Settings > Apps or Control Panel. Your saved hosts may be removed unless you enable cloud sync.

Can I disable termius.exe?

Yes, you can close Termius and disable startup in Task Manager. To stop background syncing, discontinue cloud sync in Termius Settings.

Why is termius.exe running at startup?

Termius may be configured to launch at Windows startup. Disable it in Task Manager -> Startup tab, or uninstall Termius if you don’t want it to launch automatically.

Why are there multiple termius.exe processes?

Termius uses a multi-process model where each session or task may run in its own process. This improves stability and isolation; use the app’s Task Manager to inspect each process.
