Verdict Suspicious

Analyzed , 1 month ago

Is Setup.exe safe? Treat it as suspicious.

Unsigned installer with three YARA rule matches but zero antivirus detections.

Why Suspicious? unsigned executable.

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

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

Treat as unverified; obtain a code-signed copy from the legitimate source before execution.

What to do now4 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.

If you already installed it

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

Questions & answers

Short answers to the 6 questions people ask most about this file.

Is Setup.exe safe, or is it malware?
Setup.exe is rated Suspicious: some signs point to a problem, but nothing confirms it is harmful. No antivirus engine flags it; the caution comes from other evidence, such as who made it, how widely it is used or what it did in a test run. 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.
What is Setup.exe?
Setup.exe is a software installer, about 20.5 kB. It carries no version information saying what it is or who made it. VirusTotal first saw it on Aug 10, 2026.
How many antivirus engines detected Setup.exe?
None of the 62 antivirus engines that checked it flag Setup.exe. A clean antivirus result is not proof of safety; the caution comes from other evidence, such as who made it, how widely it is used or what it did in a test run.
I already downloaded and installed Setup.exe — what should I do?
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 Setup.exe?
The SHA-256 fingerprint of Setup.exe is 84515aff4016a01ef0e22512465d93590432aada8cf36b7555e37e617c0c95d7, and its MD5 is 3eed93bc6fe75cdb4daa8ab236fc2a97. 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 Setup.exe?
This report reflects the scan on Aug 31, 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.

This report and its SHA-256 fingerprint are public, so the next person who checks the same file gets an instant answer; documents and images are listed by type instead of their file name. A file we had not seen before is uploaded to VirusTotal, whose security partners and subscribers can download it; MalwareTips deletes its own copy after the scan.
