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.

78%Confidence
High
Reasoning

The detection pattern matches the low-trust-only false-positive shape: a lone low_trust engine flagged the file while tier-1 engines stayed clean. The file is unsigned with no signer history, yet behaviour telemetry shows zero offensive techniques and no malicious sandbox verdict. Medium prevalence over 211 days without external-intel corroboration further reduces risk. No RAG matches or triggered heuristics add weight either way.

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.onlyLowTrustFlagging=true with tier1Malicious=0 (APEX low_trust only)

  2. signing.signed=false and signing.signerStats.found=false

  3. behaviour.hasMaliciousSandboxVerdict=false and behaviour.offensiveCount=0

  4. prevalence.classification=medium (5 submitters) with externalIntel.yaraify.ruleCount=0

Points in its favour
  • tier1Malicious=0 across 17 high-trust engines
  • no malicious sandbox verdict
  • no contacted malicious hosts
Recommended action

Proceed with normal caution; the single low-trust flag is consistent with known false-positive patterns on unsigned executables.

What to do now

This file looks safe based on everything we checked.

  1. This file is safe to use.

  2. Good habit: only download files from the official website or an app store.

  3. Keep your antivirus and Windows updates switched on so you stay protected.

Safety FAQ

Common questions about W2UTrigger.exe, answered from the scan data above.

  • W2UTrigger.exe appears safe. 73 of 74 antivirus engines report it clean, with only 1 low-confidence detection that read as false positives. As a habit, only run files you downloaded from the official source, since attackers sometimes distribute trojanised copies of legitimate software under the same name.
  • W2UTrigger.exe is a Windows executable program, about 81 KB. Our analysis found no threat indicators for it. A file's name can be reused by different files, so we identify it by its cryptographic hash (below).
  • 1 of 74 antivirus engines flagged W2UTrigger.exe, 1 of them as outright malicious. A small number of detections can include false positives, so we weigh which engines flagged it and what else the file does, not just the raw count.
  • The SHA-256 hash of W2UTrigger.exe is bb70bef59a99d02f3191bcd3f4db5fb7d73dcbbba4f52cdd331ae251df6be805, and its MD5 is 60d2109a97d573f21c9ec831069a2983. 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.
  • Based on this scan, yes — W2UTrigger.exe shows no threat indicators. The important caveat is source: make sure you downloaded it from the official website or a trusted store, because attackers sometimes distribute malware-laced copies under a legitimate file's name. If your own antivirus flags it while we report it clean, that is most often a false positive, but verify the source before overriding your antivirus.
  • This report reflects the scan run on July 17, 2026. Because a file's hash never changes, the identity of W2UTrigger.exe 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.
