Verdict Suspicious

Analyzed , 1 hour ago

Is Quant.msi safe? Treat it as suspicious.

This unsigned, rarely seen crypto-themed installer is flagged as a trojan by two major antivirus engines and contacts an unusual server endpoint for fetching an agent script.

Read the whole reasonShow less

Why Suspicious? 3 antivirus engines flag it; nothing else confirms it.

Limited evidence · One sign points to a problem; nothing else confirms it.

Don't install it until you know where it came from

Avoid installing this package unless you can confirm it comes from the product's official, verified source; if installed, remove it and run a full scan with your protection enabled.

What to do now5 steps

Some signs point to a problem, but nothing confirms it is harmful. Treat it with caution.

What to do

  1. Don't install it unless you're sure where it came from.

  2. Check where you got it: an unexpected attachment, a link someone sent you or a re-upload is a red flag.

  3. If you can't confirm where it came from, delete it. If you need the program, download it again from the publisher's own website.

  4. It is less than a day old. If you're unsure, scan it again in a few days; antivirus engines often catch up on new files.

If you already installed it

  1. Stop using it, run a full scan with your antivirus and watch for unexpected behavior or security alerts.

MT AI Engine · Verdict analysis

The reasoning behind this verdict

Analyst conclusion

ESET-NOD32 and Ikarus, two major antivirus engines, detect this Windows Installer package as a trojan, and Google flags it too. It is unsigned, was first seen on Oct 26, 2026 from a single source, and during sandbox runs it reached a server on a non-standard port requesting an agent script. The combined sandbox verdict was clean, so the evidence is mixed but leans hostile.

Where this verdict could be wrong2 caveats
  • The combined sandbox verdict was clean and no high-risk techniques were recorded, so the installer may be an unsigned cryptocurrency trading app that the two engines flagged heuristically.
  • Our static analysis found no hostile patterns inside the package, and no contacted host is listed as malicious in our records.

These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.

Is Quant.msi safe, or is it malware?
Quant.msi is rated Suspicious: some signs point to a problem, but nothing confirms it is harmful. 3 of the 58 antivirus engines that checked it flag it. Don't install it unless you're sure where it came from. If you need the software, download a fresh installer from the developer's own website.

How many antivirus engines detected Quant.msi?
3 of the 58 antivirus engines that checked it flag Quant.msi, including ESET and Ikarus. We weigh which engines flagged it and what else the scan found, not just the count.
What should I do if I already installed Quant.msi?
No infection is confirmed: the rating is a caution, not a malware finding. 1) Check where it came from. If you can't confirm the source, delete it. 2) Run a full scan with your security software. 3) If the scan finds something, follow its removal steps and change passwords you typed on the device since then.
What is the SHA-256 hash of Quant.msi?
The SHA-256 fingerprint of Quant.msi is 7cfc7235f99bc8c7e1b49f12cfc33c1c789084d5d6f49bea40917ffb330a7515, and its MD5 is f4ea7939ff03372c34e7678581febc46. Two files with the same SHA-256 are identical, so use it to check you have exactly this file, not just one with the same name.
How up to date is this analysis of Quant.msi?
This report reflects the scan on Oct 26, 2026. A file's fingerprint never changes, but antivirus engines keep learning, so a rating can change later. To get a newer result, scan the file again: we refresh the antivirus results when the saved ones are out of date.
