File verdict·Decided by the MT AI Engine
Our call

Safe

This file is a legitimate installer signed by Open Text Corporation, with generic heuristic detections likely resulting from its installation behavior rather than actual malicious intent.

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.

90%Confidence
Very high
Reasoning

The file is correctly signed by a trusted publisher, Open Text Corporation. The detections are limited to two tier-2 engines and are generic in nature, which is a classic indicator of a false positive for installers. The observed process injection techniques are consistent with legitimate setup procedures. No malicious network activity or sandbox behavior was detected, and the file's behavior is consistent with known benign installers from this publisher.

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. Signed by 'Open Text Corporation' (signing.verified=true)

  2. 0/17 tier-1 engines flagged the file as malicious (engines.tier1Malicious=0)

  3. All malicious detections are generic/heuristic (engines.topDetections[].labelFlags)

  4. No malicious sandbox activity or contacted hosts (behaviour.hasMaliciousSandboxVerdict=false)

  5. Similar hashes with matching signer are verdicted as safe (similarHashes[0].verdict='safe')

Points in its favour
  • Verified digital signature

Safety FAQ

Common questions about MailStoreHomeSetup.exe, answered from the scan data above.

  • MailStoreHomeSetup.exe appears safe. 72 of 74 antivirus engines report it clean, with only 2 low-confidence detections that read as false positives. It carries a verified digital signature from Open Text Corporation. 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.
  • MailStoreHomeSetup.exe is a Windows executable program, about 1000 KB. Our analysis found no threat indicators for it. It carries a verified digital signature from Open Text Corporation. A file's name can be reused by different files, so we identify it by its cryptographic hash (below).
  • 2 of 74 antivirus engines flagged MailStoreHomeSetup.exe, 2 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 — MailStoreHomeSetup.exe carries a valid digital signature from Open Text Corporation, 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 MailStoreHomeSetup.exe is d70f78dbdfa3ac8352b978791deef51f047fee9c1c9ccc0b73c402ce5087de6b, and its MD5 is ad92ad6752754870cfd17a9b51331eb7. 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 — MailStoreHomeSetup.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 July 17, 2026. Because a file's hash never changes, the identity of MailStoreHomeSetup.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.
