The verdict, reasoned out.

Not a rules engine. The MT AI Engine reads every signal we collected, weighs them against history, and commits to an answer.

Reasoning

The file presents a clean profile across all high-trust detection engines. Zero malicious detections among 65 reporting engines, with tier-1 vendors unanimously reporting undetected status, indicates the archive is not recognized as a known threat. The absence of sandbox execution data is expected for ZIP files, which do not execute directly. No external intelligence sources (CIRCL, MalwareBazaar, YARAify) corroborate any threat. The rare_new prevalence classification reflects limited submission history rather than suspicious behaviour. Unsigned status and lack of signer history are typical for legitimate portable-application archives.

Key signals · 5

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

  1. engines.tier1Malicious=0; 12 tier-1 engines (Avast, BitDefender, Kaspersky, Microsoft, ESET-NOD32, Fortinet, others) all undetected

  2. engines.malicious=0 across all 65 reporting engines; no malicious labels present

  3. prevalence.classification=rare_new (2 submitters); no prior reputation history

  4. signing.verified=false; unsigned file with no signer history to establish trust

  5. externalIntel: CIRCL=false, MalwareBazaar=false, YARAify.ruleCount=0; no external corroboration of threat

Points in its favour
  • All 12 tier-1 antivirus engines report undetected/clean
  • Zero malicious detections across 65 reporting engines
  • No external threat intelligence corroboration (CIRCL, MalwareBazaar, YARAify all negative)
  • No sandbox malicious behaviour recorded
  • No adversarial input flags in filename or metadata
What to do

This file is safe to use based on comprehensive antivirus scanning and absence of malicious behaviour signals. If you extracted the archive and encounter unexpected behaviour, re-submit the extracted files for analysis.

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.
