What is mbam-setup.exe?

The genuine mbam-setup.exe file is a software component of Malwarebytes Anti-Malware by Malwarebytes.
"Mbam-setup.exe" is the executable setup file to install Malwarebytes Anti-Malware that can be downloaded from their website. It executes from "C:\Users\%USERNAME%\Downloads" or "...\Desktop", unless a different folder was specified. This is different from "mb3-setup-1878.1878-", the download for Malwarebytes' new product, Malwarebytes 3.0 Premium that combines Anti-Malware, Anti-Exploit, and Endpoint Security and includes real-time protection instead of just a manually run scan-and-fix. (If the 14-day free trial for 3.0 Premium expires it reverts to manual mode.) In a successful setup, this file is removed, so if it is still present either download it again for the latest version or simply delete it. Malwarebytes was founded in 2008 by Marcin Kleczynski and Bruce Harrison and recently relocated to Santa Clara, CA due to rapid expansion.
