Safe
This old Installer.exe has a positive reputation but flags as generic trojan by 3 engines (no tier-1 hits), with suspicious network behaviors like via-tor access.
a453b3ea8d8133531f…e100908c1aThe 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 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.
- 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.
- 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.
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.

Safety FAQ
Common questions about Installer.exe, answered from the scan data above.
- Installer.exe appears safe. 73 of 76 antivirus engines report it clean, with only 3 low-confidence detections 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.
- Installer.exe is a Windows executable program, about 5.1 MB. 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).
- 3 of 76 antivirus engines flagged Installer.exe, 3 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 Installer.exe is a453b3ea8d8133531fad26b18701c694c324cc201e3069d07e99f0e100908c1a, and its MD5 is a7c8cf1d50ebe630a7d0c47686a0abbf. 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 — Installer.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 April 20, 2026. Because a file's hash never changes, the identity of Installer.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.
