What is sidekick-helper.exe?
sidekick-helper-exe is the background helper component for the Sidekick application. It runs as a lightweight Windows process to coordinate notifications, status updates, and cross-component communication. By handling background tasks, it keeps the Sidekick experience responsive without requiring the main UI to stay open.
The process is designed as a small, sandboxed helper that runs with lower priority, launching at user login or with Sidekick. It delegates network calls, local event handling, and inter-process messaging to avoid blocking the UI thread.
Quick Fact: Sidekick uses a modular helper to run background jobs and relay status changes to the UI, ensuring smooth operation even when the main window is minimized.

How to Tell if sidekick-helper.exe is Legitimate or Malware
- File Location:: Must be in
C:\Program Files\Sidekick\Sidekick Helper\sidekick-helper.exe or C:\Program Files (x86)\Sidekick\Sidekick Helper\sidekick-helper.exe. Any sidekick-helper.exe elsewhere is suspicious.
- Digital Signature:: Right-click the file in Explorer → Properties → Digital Signatures. Should show "Sidekick Inc" or a trusted publisher.

Beware of similarly-named files like "sidekick.exe" or "sidekick-helper32.exe" from untrusted sources.
