We ran both products on the same Windows 11 reference hardware (Intel i5-12450H, 16 GB DDR5, NVMe SSD) for a 7-day side-by-side evaluation.
| Malwarebytes Premium | ClamWin Free Antivirus | |
|---|---|---|
| Idle RAM footprint | 80-130 MB | N/A (on-demand) |

| Full scan duration | 9 min | 46 min (single-threaded) |
For users with modern hardware (2020+), the performance difference is usually imperceptible during daily use — both products idle quietly and scan without disrupting active work. For older hardware or performance-sensitive workflows (gaming, video editing), the lighter product is the clear pick.
