Combo Cleaner is a security and cleaning utility for detecting malware and clearing device storage, available for Android, iOS, macOS and Windows. Its tools and paid features vary by platform. On Mac, the antivirus checks for malware and adware, with definitions updated hourly, but removing detected infections requires the paid version. The free Mac utilities are Disk Cleaner, Big Files Finder and Duplicate Files Scanner. Its Privacy Scanner can identify browsing history, cookies and other private data in Safari, Chrome, Firefox and Opera; removing those items requires the full version. Windows protection includes on-demand and real-time scanning, selected-folder anti-ransomware protection and web protection. The Android app includes malware scanning, web protection, storage and photo cleaning, and app management; anti-malware and app manager features are paid. The iOS app includes photo cleaning, web security, identity breach checking, and SMS and calendar link protection, with three security features paid. A free version costs nothing, but can show detected items without removing them. A 7-day free trial is also listed; full and custom antivirus scans are unavailable during it.
