Is LuluNotes_Setup.exe safe?
Unsigned NSIS installer with one tier-1 detection and no sandbox malice.
Four of 75 engines flag the file, one of them tier-1. The sample is unsigned, shows only ambient behaviour, and matches an imphash previously seen in safe verdicts.

Before installing
Do not install it until the source and publisher can be verified independently.
If you already installed it
Stop using it, scan the device, and watch for unexpected behavior or security alerts. Download a fresh installer from the developer's official site or an official app store.
Intelligence
The saved assessment, checked against the scan evidence and recorded coverage.
The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
Four of 75 engines flag the file, one of them tier-1. The sample is unsigned, shows only ambient behaviour, and matches an imphash previously seen in safe verdicts.
The single tier-1 detection (Ikarus) is offset by 16 other tier-1 engines reporting clean. No sandbox malice, no dropped malicious children, and no external-intel corroboration exist. The unsigned state and installer nature keep the file in mixed-signals territory rather than safe or malicious.
What We Detected
Four engines (Ikarus tier-1, Gridinsoft, Malwarebytes, Google) report malicious labels; the remaining 66 engines are silent. The file is an unsigned NSIS installer with high-entropy overlay but no packers detected.
Threat Behavior
Sandbox execution produced only ambient techniques and one privilege-related call (T1134). no complete contacted-host reputation result was available, no malicious child files, and no persistence indicators were observed.
What To Do Now
Keep endpoint protection enabled. If the file is not required, delete it or obtain a signed copy from the vendor. Monitor any further detections from additional engines.
- 16 tier-1 engines clean
- no sandbox malice
- no dropped malicious children
- unsigned executable
- tier-1 detection present
- newly prevalent installer
Treat as suspicious; do not run without additional verification or a signed build from the publisher.

Complete means the check returned a usable result. It does not mean the file is safe.

What this file does
Observed actions and their security significance
High concern: Changed an auto-start location that can make code run after sign-in or restart.
High concern: Manipulated how the operating system loads code, which can redirect execution.
Moderate concern: Contained obfuscated or packed code that makes inspection harder.
Moderate concern: Runs hidden system commands (script or shell).
Moderate concern: Communicated over a common application protocol; malware can use this for command-and-control.
Moderate concern: Scans through your files and folders.
Note: Reads your Windows user-account details.
These are observed capabilities from an isolated analysis. A technique does not prove malicious intent on its own, and the file never ran on your device.
