Issue

During the installation of Mendix Studio Pro 11.12.0, the antivirus software detects and quarantines the file main-lMW5YPQT.js, identifying it as a Trojan.

Environment

Studio Pro 11.12.0

Cause

Antivirus software occasionally flags minified and bundled JavaScript files due to heuristic detection patterns, as the compressed, heavily optimized code can superficially resemble malicious scripts, even when the content is entirely safe.

Solution / Workaround

The file has been confirmed as a false positive. The file main-lMW5YPQT.js is a legitimate part of the Mendix 11.12.0 installation, it is a standard bundled JavaScript file generated by the Mendix build pipeline. To resolve the issue and prevent it from occurring in future installations, follow the steps below:

• Add an exception or whitelist for main-lMW5YPQT.js in the antivirus software to prevent it from being quarantined in future Mendix installations.
• If the antivirus vendor requires further confirmation, submit the file directly to them as a false positive. Most vendors provide a submission portal for this purpose.
