Balena Etcher Image Flasher
etcher.exe is safe. Balena Etcher is a legitimate image flashing tool that runs to write OS images to USB drives or SD cards, with optional verification and updater components.
etcher.exe is the Windows executable for Balena Etcher, a cross‑platform image flashing tool. It coordinates the user interface, image validation, and the actual flashing process to USB drives or SD cards. Etcher runs as one or more small processes during a flash, and it can run in the background for updates or verifications.
Etcher uses a multi‑process approach: a main process handles the UI, while worker processes perform image validation and the write/verification steps. It uses OS APIs to safely access removable media, ensuring the wrong drive is not overwritten and that progress is reported to the user.
Quick Fact: Etcher started as a cross‑platform image flashing tool designed to minimize accidental writes by using explicit drive selection and a verification step.
Yes, etcher.exe is safe when downloaded from Balena's official sources (balena.io) or properly distributed installers.
The real etcher.exe is NOT a virus. However, malware can masquerade with similar names. Always verify source and signature.
C:\Program Files\balena-etcher\etcher.exe or C:\Program Files (x86)\balena-etcher\etcher.exe. Any etcher.exe elsewhere is suspicious.Red Flags: If etcher.exe is located in unusual folders (Temp, AppData\Roaming, or System32), runs when Etcher isn't open, has no digital signature, or uses excessive resources constantly, scan your system with antivirus software immediately. Beware of similarly-named files like "etcher32.exe" from untrusted sources.
Etcher runs when you are flashing an image, verifying a write, or when the built‑in updater checks for new versions. It may also stay resident to monitor connected drives or show progress in the system tray.
Reasons it's running:

Quick Fixes:
1. Cancel any active flash, then reconnect the USB drive and restart Etcher

No, the legitimate etcher.exe from Balena is not a virus. Always verify the install path: C:\Program Files\balena-etcher\etcher.exe or C:\Program Files (x86)\balena-etcher\etcher.exe and ensure a valid signature from Balena.
CPU usage spikes during writing or verification. If it stays high when idle, check for a stuck flash, a problematic image, or malware posing as etcher.exe; run a malware scan and verify the signed binary.
Yes, uninstall Balena Etcher from Windows Settings or Control Panel. Your flashing history may remain in Etcher, but local images are not typically deleted unless you choose to remove them.
Yes. Use Task Manager → Startup to disable Balena Etcher from launching on startup. This prevents background checks or idle services from loading at boot.
Etcher may auto-detect removable media for quick flashing. If you don’t want this behavior, disable auto-detection in Etcher's settings or unplug drives before opening Etcher.
Select the image, choose the right drive, avoid dramatic changes to internal disks, and begin the flash. Always verify the write if the image source is trusted, and safely eject the drive after completion.
