Quick Answer
ts3client_win64.exe is safe. It's the official TeamSpeak 3 Client executable that handles voice communication, server connections, and the user interface for TeamSpeak 3 Client.
What is ts3client_win64.exe?
ts3client_win64.exe is the main executable for the TeamSpeak 3 Client on 64‑bit Windows. It manages user authentication, server connections, voice capture and playback, channel navigation, and plugin interfaces. The client uses multiple threads and background tasks to keep audio streaming stable and responsive.
The TeamSpeak 3 Client uses a multi-threaded architecture. ts3client_win64.exe starts the UI, manages network sockets (UDP/TCP) to TeamSpeak servers, handles voice encoding/decoding, and loads plugins. It can spawn separate worker threads for audio and event handling to maintain responsiveness.
Quick Fact: TeamSpeak 3 introduced scalable voice latency and channel-based permissions long before many comparable VoIP apps.

How to Tell if ts3client_win64.exe is Legitimate or Malware
- File Location: Must be in
C:\Program Files\TeamSpeak 3 Client\ or C:\Program Files (x86)\TeamSpeak 3 Client\. Any ts3client_win64.exe outside these folders is suspicious.
