MT AI Engine · our arbiter

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 exhibits a clean profile across all detection channels. Zero malicious detections from any engine tier, combined with common_old prevalence (147 submitters, 155 submissions), indicates this is an established benign artifact. The .reg extension and minimal 300-byte size are consistent with a Windows registry import/export file, not executable malware. Unsigned status is normal for registry files. No external intelligence (CIRCL, YARAify, MalwareBazaar) corroborates any threat. The absence of any heuristic triggers or behaviour data, paired with universal tier-1 engine silence, rules out both known and novel malware.

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; tier1ReportedClean=17 (Avast, AVG, Avira, BitDefender, DrWeb, Emsisoft, ESET-NOD32, F-Secure, Fortinet, GData, Ikarus, Kaspersky, Microsoft all undetected)

  2. prevalence.classification='common_old' with 147 unique submitters and 155 submissions — established benign prevalence

  3. engines.malicious=0, engines.suspicious=0, onlyLowTrustFlagging=false — no detections across any trust tier

  4. signing.verified=false, unsigned file; no signer history; no brand mismatch — clean metadata

  5. externalIntel: circl.hit=false, yaraify.ruleCount=0, malwareBazaar.hit=false — no researcher corroboration of malice

Points in its favour
  • Universal tier-1 engine silence (17 tier-1 vendors undetected)
  • Common_old prevalence (147 submitters, 155 submissions over 246 days)
  • No external intelligence corroboration (CIRCL, YARAify, MalwareBazaar all negative)
  • Minimal file size (300 bytes) consistent with benign registry artifact
  • No sandbox, behaviour, or host-contact malice signals

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.
