CCleaner Pro Service
ccleaner-pro-service.exe is the background service that powers CCleaner Pro’s automated maintenance tasks. It runs quietly as a Windows service to execute scheduled cleaning, privacy sweeps, and optimization routines without user interaction. It coordinates with the main CCleaner app to apply configured cleaning profiles and keep systems tidy between manual runs.
The executable hosts the Pro edition’s housekeeping routines, including automatic browser cache cleanup, registry trimming, drive space analysis, and privacy sweeps. It communicates with the main app to apply configured schedules and ensure ongoing maintenance without manual triggers.
CCleaner Pro Service is a legitimate component published by Piriform for CCleaner Pro. When installed from official sources, it runs as a signed Windows service to perform automated maintenance tasks such as cleanup, privacy sweeps, and optimization. If detected in the expected program path and signed correctly, it is safe; issues typically arise only from tampered or counterfeit builds.
While the file is legitimate when sourced from official CCleaner Pro installers, malicious actors sometimes imitate or replace legitimate components. An unsafe copy may appear under unusual folders, lack a valid signature, or differ in size from the official binary. Verifying origin and signature is essential to rule out malware.
Red Flags: Unsigned signature, unexpected file location outside the Program Files path, mismatched file size, or a digital certificate from an unknown issuer are strong indicators of tampering.
Reasons it's running:
ccleaner-pro-service.exe is the background service that powers CCleaner Pro's automated maintenance tasks, such as scheduled cleaning, privacy sweeps, and optimization, running without a UI.
Yes, when installed from official sources, it is a legitimate component designed to run maintenance tasks in the background securely.
You can disable it, which stops automatic maintenance, but you can still run manual cleans from CCleaner Pro when needed.
Typically under C:\Program Files\CCleaner Pro\ccleaner-pro-service.exe or C:\Program Files (x86)\CCleaner Pro\ccleaner-pro-service.exe.
Update CCleaner Pro via the official CCleaner Pro installer or update channel; the service will be updated as part of the program package.
Verify the digital signature matches Piriform, ensure the file location is correct, and add a safe-exception for the executable in your antivirus software if it is legitimate.
