Reasoning

The file presents as Installer.exe, a Win32 PE executable over 5MB, first submitted over 10 years ago with strong positive reputation (176) and no code signature. Out of 76 engines, only 3 flagged it malicious—Jiangmin calls it Trojan.Generic.haljt, SentinelOne sees suspicious PE traits, and low-trust Trapmine gives a low ML score—while 17 tier-1 engines (Avast, BitDefender, ESET, etc.) and 68 others report clean. Network tags like via-tor, overlay, and direct-cpu-clock-access raise flags for potential hidden malicious behavior if run. No external intel hits, so the few detections without tier-1 backing suggest a possible false positive on this aged file, but caution is warranted. Quarantine it and avoid execution until further analysis.

Points in its favour
  • Positive reputation score of 176 indicates community trust.
  • First seen 3805 days ago (2015), with consistent clean scans over time.
  • All 17 tier-1 engines (BitDefender, Kaspersky, ESET, etc.) report clean.
  • 68 engines undetected out of 76 total, showing broad consensus.
  • No hits in MalwareBazaar, YARAify, or CIRCL threat intel.
Points against
  • Jiangmin (tier2) detects it as Trojan.Generic.haljt, a generic malware label.
  • SentinelOne (tier2) flags Static AI - Suspicious PE based on file structure.
  • Trapmine (low-trust) scores it suspicious.low.ml.score via ML heuristics.
  • Network tag 'via-tor' suggests potential anonymous malicious communication.
  • Network tag 'direct-cpu-clock-access' hints at timing evasion or mining behavior.
  • PE imphash a8fd72e864d14b8484dd49e800fd3a36 seen in some suspicious files.
What to do

Quarantine or delete Installer.exe immediately—do not run it. Resubmit the hash to MalwareTips or your AV for a second opinion, as the low detection count and strong clean signals from tier-1 engines suggest it may be safe.

2 contradictions resolved by the scoring engine

Only low-trust / heuristic engines flagged this file
3 engines from the heuristic / generic-AI set flagged it. No tier-1 engine agreed.
Verdict treated these as likely false positives.
MT AI Engine read "suspicious", displayed verdict is "safe"
A ground-truth gate (admin override, MalwareBazaar, empty-file) or the low-confidence display rule shifted the final call.
Displayed verdict tracks the harder evidence.

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.
