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.

85%Confidence
Very high
Reasoning

The single malicious detection comes from a low-trust engine with a generic grayware label and no tier-1 support. The file is properly signed by ALCPU, shows typical Inno-Setup installer behaviour (process injection, persistence, direct-IP contact during install), and has no malicious dropped children or sandbox verdicts. Prevalence is high (common_new) with explicit researcher confirmation of no threat. These factors outweigh the heuristic triggers.

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.onlyLowTrustFlagging=true and tier1Malicious=0 (CrowdStrike grayware only)

Points in its favour
  • Verified signature by ALCPU
  • High prevalence common_new
  • Zero tier-1 malicious detections
  • Clean sandbox and dropped children
Recommended action

Safety FAQ

Common questions about Core-Temp-setup-v1.20.1.150.exe, answered from the scan data above.

  • Core-Temp-setup-v1.20.1.150.exe appears safe. 74 of 75 antivirus engines report it clean, with only 1 low-confidence detection that read as false positives. It carries a verified digital signature from ALCPU. 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.
  • Core-Temp-setup-v1.20.1.150.exe is a Windows executable program, about 1.6 MB. Our analysis found no threat indicators for it. It carries a verified digital signature from ALCPU. A file's name can be reused by different files, so we identify it by its cryptographic hash (below).
  • 1 of 75 antivirus engines flagged Core-Temp-setup-v1.20.1.150.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.
  • Yes — Core-Temp-setup-v1.20.1.150.exe carries a valid digital signature from ALCPU, which confirms the file hasn't been tampered with since that publisher signed it. A valid signature is a positive signal, but note that malware is occasionally signed with stolen or abused certificates, so it isn't proof of safety on its own.
  • The SHA-256 hash of Core-Temp-setup-v1.20.1.150.exe is 26e9a2b20608f00f43a44d0f7fa57e70a832087c3d4a9aa1d8dc73078d9b5606, and its MD5 is 7edd792d56093efe9b7ad08fe3dcaf13. 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 — Core-Temp-setup-v1.20.1.150.exe shows no threat indicators and is properly signed. 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 May 26, 2026. Because a file's hash never changes, the identity of Core-Temp-setup-v1.20.1.150.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.
