Is NSX_Optimizer.exe safe?
Unsigned 60 kB PE triggers one tier-1 engine and shows an offensive MITRE technique.
Nine of 75 engines flag the file, including Microsoft tier-1. No code signature or established signer history exists, and sandbox coverage is absent. The single prior similar-hash verdict was also suspicious.

Before running
Do not run it until the source and publisher can be verified independently.
If you already ran it
Stop using it, scan the device, and watch for unexpected behavior or security alerts. Get a fresh copy from the developer's official site or an official app store.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
Nine of 75 engines flag the file, including Microsoft tier-1. No code signature or established signer history exists, and sandbox coverage is absent. The single prior similar-hash verdict was also suspicious.
A lone tier-1 detection paired with four tier-2 detections and an offensive MITRE technique (T1620) outweighs the majority clean tier-1 results. The file is unsigned, eliminating any trusted-publisher defense. The single RAG match is weak because it is only a filetype collision. Missing sandbox and host-reputation data leave the behavioural picture incomplete, so the balanced evidence lands in the suspicious band.
What We Detected
9 of 75 engines report malicious, one of them tier-1 (Microsoft). The sample is an unsigned 60 kB PE with no signer history. Behaviour analysis recorded the offensive technique T1620 but no sandbox runs completed.
Threat Behavior
Without sandbox output or contacted-host reputation, the only concrete malicious indicators are the engine detections and the MITRE technique. No dropped children or external-intel hits were observed.
What To Do Now
Do not run the file. Keep endpoint protection enabled and submit the sample to a sandbox service for deeper behavioural inspection before any further evaluation.

These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Majority of tier-1 engines clean
- No external-intel corroboration
- Unsigned executable
