MT AI Engine · Verdict analysis

The reasoning behind this verdict

The MT AI Engine weighs every signal from this scan — antivirus detections, sandbox behaviour, code signing, prevalence and historical matches — to reach a single, evidence-based verdict.

45%Confidence
Moderate
Reasoning

All 74 engines returned clean results, including 17 tier-1 engines. The file is unsigned and has only a single submission recorded today. No sandbox behaviour, dropped children, or external intelligence hits exist. The combination of zero detections and complete absence of reputation data prevents a confident classification.

Key signals · 4

Each signal cites a concrete token from the evidence the arbiter saw — engine name, MITRE technique, signer string, or an exact count.

  1. engines.malicious=0 with tier1Malicious=0 across 17 tier-1 engines (Avast, AVG, Avira, BitDefender, DrWeb, Emsisoft, ESET-NOD32, F-Secure, Fortinet, GData, Ikarus, Kaspersky, Microsoft)

  2. prevalence.classification='rare_new' and file.ageDays=0

  3. signing.signed=false with no signerStats history

  4. filenameAnalysis.hasInstallerHint=true and looksLikePortable=true

Points in its favour
  • Zero engine detections
  • No external intelligence hits
  • No malicious behaviour observed
Points against
  • Unsigned file
  • rare_new prevalence
  • zero prior submissions
Recommended action

Treat as unknown until additional reputation or sandbox data becomes available; do not execute without further verification.

What to do now

There isn't enough information to give this file a clear rating.

  1. Be cautious — an unknown rating is not the same as a clean bill of health.

  2. Only run it if it came directly from the official maker of the software.

  3. When in doubt, don't open it — or scan it again later once it's more widely seen.

How widely this file has been seen

Barely seen in the wild and first surfaced recently. This is the footprint of targeted malware the AV industry hasn't signatured yet — extra scrutiny is warranted.

Safety FAQ

Common questions about NMInstall.zip, answered from the scan data above.

  • We can't give NMInstall.zip a confident verdict yet — too few engines have an opinion on this exact file. Uncommon or brand-new files often show little coverage before vendors catch up, so treat it as untrusted: don't run it unless you're certain of the source.
  • NMInstall.zip is a software installer (application/x-zip-compressed), about 34.8 MB. We identify a file by its cryptographic hash rather than its name, because the same filename can be reused by completely different files — the hash below is the reliable fingerprint.
  • None — all 74 antivirus engines we queried report NMInstall.zip as clean. That's reassuring, though brand-new malware can briefly evade detection before vendors add signatures, so we also weigh the file's behaviour and reputation.
  • The SHA-256 hash of NMInstall.zip is d0bf00ac475a53f787e040078868332f445603593974acd6e0fba3fdf1f96d44, and its MD5 is 302a12b59e3605f266543011e4ee6ddf. This hash is the file's unique fingerprint — two files with the same SHA-256 are identical. Use it to confirm you're looking at exactly this file (not just one with the same name) when comparing against antivirus databases or a download's published checksum.
  • This report reflects the scan run on July 4, 2026. Because a file's hash never changes, the identity of NMInstall.zip is fixed — but antivirus coverage improves over time, so a file that looks clean today can pick up detections later (and vice-versa). If you need the latest picture, MalwareTips staff can re-run the analysis from scratch.

Files are processed in a streaming pass-through — MalwareTips never stores the binary on its servers. Only the scan result (hash, detections, verdict) is retained so the next person who scans the same file gets an instant answer. If you ran this file on your computer and are worried, scan your system with an up-to-date antivirus and change critical passwords from a different device.
