How to Tell if whatsapp-launcher is Legitimate or Malware
- File Location:: Must be in
C:\Program Files\WhatsApp\WhatsApp.exe or C:\Program Files (x86)\WhatsApp\WhatsApp.exe. Any launcher elsewhere is suspicious.
- Digital Signature:: Right-click the file in Explorer → Properties → Digital Signatures. Should show a trusted signer like Meta Platforms, Inc. or WhatsApp, Inc..

- Background Notifications: WhatsApp relies on background processes to push messages and status updates even when minimized.
- Startup Program: WhatsApp can be configured to launch on Windows startup, which keeps the launcher running in the background.
- System Tray Listener: The launcher maintains a system tray icon to show unread messages and quick reply options.
- Background Sync: Even when the app isn’t open, background sync tasks keep chats up to date and media ready for view.
