No, teamviewer.exe is not a virus when it's the legitimate version from TeamViewer GmbH. However, it can be exploited by scammers and attackers. Verify it's located in C:\Program Files\TeamViewer\ and digitally signed by TeamViewer GmbH. If found elsewhere or unsigned, it may be malware disguising itself as TeamViewer.
TeamViewer uses 20-40% CPU during active remote sessions because it continuously captures, compresses, and transmits your screen. This is normal. High CPU with no active connection may indicate multiple instances running, an outdated version, or malware. Check for active connections, update to the latest version, and verify the process is legitimate.
Yes, you can safely delete TeamViewer by uninstalling it through Windows Settings → Apps → Installed apps. If you don't use remote access or remote support features, it's recommended to remove it to eliminate potential security risks. Check with your IT department first if on a work computer.
Yes, you can disable TeamViewer from auto-starting by opening TeamViewer → Extras → Options → General → Uncheck "Start TeamViewer with Windows." To disable the service completely, open services.msc, find TeamViewer service, set to Disabled, and stop it. This prevents both the application and background service from running.
TeamViewer runs at startup if "Start TeamViewer with Windows" is enabled in settings, or if the TeamViewer service is configured for unattended access. This is intentional for users who need remote access capabilities immediately when the computer boots. You can disable auto-start in TeamViewer Options → General settings.
TeamViewer itself uses strong 256-bit AES encryption and is secure when properly configured. However, it becomes unsafe if you use weak passwords, fall for scammer tricks, or allow unauthorized access. Enable two-factor authentication, use strong passwords, never give access to unsolicited callers, and disable unattended access if not needed.
Active TeamViewer connections display a prominent blue window border around your screen, show a connection status window, and display the remote user's information. The TeamViewer icon in the system tray also changes color (green when connected). You can view connection history in Extras → Options → Advanced → Show advanced options → Open log files.
teamviewer.exe is the main application that runs when you launch TeamViewer manually. TeamViewer_Service.exe is the Windows service that runs in the background to enable unattended access, allowing remote connections even when no user is logged in or when TeamViewer isn't actively running. The service uses more resources and should be disabled if unattended access isn't needed.
