Safe
Single low-trust engine flag on an unsigned executable with clean sandbox and no tier-1 detections.
bb70bef59a99d02f31…51df6be805The 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.
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.
Each signal cites a concrete token from the evidence the arbiter saw — engine name, MITRE technique, signer string, or an exact count.
engines.onlyLowTrustFlagging=true with tier1Malicious=0 (APEX low_trust only)
signing.signed=false and signing.signerStats.found=false
behaviour.hasMaliciousSandboxVerdict=false and behaviour.offensiveCount=0
prevalence.classification=medium (5 submitters) with externalIntel.yaraify.ruleCount=0
- tier1Malicious=0 across 17 high-trust engines
- no malicious sandbox verdict
- no contacted malicious hosts
Proceed with normal caution; the single low-trust flag is consistent with known false-positive patterns on unsigned executables.

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.
