What is mbam.exe?
mbam.exe is the core executable used by Malwarebytes Anti-Malware to provide real-time protection, on-demand scans, and threat remediation. It coordinates the main service, the scanning engine, and background updater components to detect and block malware on your system.
mbam.exe is part of the Malwarebytes protection stack; runs as a service and launcher for the scanning engine, updater, and UI actions. The multi-process design improves reliability and isolates threat handling.
Quick Fact: Malwarebytes uses a modular, multi-process architecture to separate protection, scanning, and updating tasks for safer operation.

Is mbam.exe a Virus or Malware?
The real mbam.exe is NOT a virus. Malware authors may mimic names, so verify location and signature.
How to Tell if mbam.exe is Legitimate or Malware
- File Location: Must be in
C:\Program Files\Malwarebytes\Anti-Malware\mbam.exe or C:\Program Files\Malwarebytes\Anti-Malware\mbamtray.exe. Any mbam.exe elsewhere is suspicious.
- Digital Signature: Right-click mbam.exe in Explorer → Properties → Digital Signatures. Should show signer 'Malwarebytes, Inc.' or 'Malwarebytes Corporation'.
- Resource Usage: Normal usage is around 1-8% CPU and tens to a few hundred MB of memory during protection or scans.
- Behavior: mbam.exe should be active when protection is enabled or a scan is running; persistent activity with no UI may indicate a problem.
