Is setup.exe safe?

Verdict
Malicious

Six high-trust engines flagged this unsigned installer, with three independently agreeing on Yomal and runtime evidence indicating possible process manipulation.

The strongest evidence is agreement among three high-trust engines on the Yomal trojan family, within 24 detections across 74 engines. The unsigned executable also exhibited techniques mapped to process injection and token manipulation, while no complete reputation check is available for its observed IP contact.

Do not install this file

Quarantine or delete this installer and keep endpoint protection enabled. If it has already executed, run a full scan and replace it only with a copy obtained directly from the official publisher.

This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.

94%Confidence

Analyst conclusion

The strongest evidence is agreement among three high-trust engines on the Yomal trojan family, within 24 detections across 74 engines. The unsigned executable also exhibited techniques mapped to process injection and token manipulation, while no complete reputation check is available for its observed IP contact.

Where this verdict could be wrong5 caveats
  • Ten tier-1 engines did not detect the file, including Avast, AVG, Avira, BitDefender, and DrWeb.
  • behaviour.hasMaliciousSandboxVerdict=false, and no persistence indicators were recorded in the single completed sandbox run.
  • droppedChildren inspected 9 files without a confirmed malicious child, although all nine child verdicts remain unknown.
  • externalIntel.yaraify.ruleCount=0 and externalIntel.circl.hit=false, so researcher-curated sources did not independently corroborate the family.
  • The sample is relatively prevalent, with prevalence.uniqueSources=689 and prevalence.timesSubmitted=756.

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

Recommended action

What this file does

Observed actions and their security significance

  • High concern: Injected code into another process, a technique that can conceal execution.

  • Moderate concern: Contained obfuscated or packed code that makes inspection harder.

  • Moderate concern: Runs hidden system commands (script or shell).

  • Moderate concern: Communicated over a common application protocol; malware can use this for command-and-control.

  • Moderate concern: Scans through your files and folders.

  • Moderate concern: Decoded or unpacked concealed content while running.

  • Note: Listed running processes; both legitimate software and malware may do this.

These are observed capabilities from an isolated analysis. A technique does not prove malicious intent on its own, and the file never ran on your device.

Threat context

How trojans work

A trojan disguises itself as something useful or harmless to trick you into running it. Once open, it does its real job in the background — anything from stealing data to opening a back door or downloading more malware.

Bottom line:The disguise is the whole trick, so a trustworthy-looking name or icon means nothing.

  1. Recovery step 01

    Don't install this file. Delete this file from the device, then empty the Recycle Bin or Trash.

  2. Recovery step 02

    If you already installed it, disconnect from the internet and start with a full antivirus scan or Microsoft Defender Offline scan. If compromise is suspected or the problem persists, use a reputable second-opinion scanner and follow incident-recovery or clean-reinstall guidance.

  3. Recovery step 03

8 evidence-based answers
Is setup.exe a virus?
Evidence-based answer
Yes — setup.exe is malicious. Do not install it. Delete this file from the device, then empty the Recycle Bin or Trash. 24 of 74 antivirus engines flag it (family: Yomal). It behaves as a trojan — malware disguised as something harmless to trick you into running it. If you've already installed it, see the removal and recovery steps below.
What is setup.exe?
Evidence-based answer
setup.exe is a software installer, about 6.1 MB. Our analysis identifies it as malicious (family: Yomal) — a trojan — malware disguised as something harmless to trick you into running it. Because a file's name and icon can be faked, the safest way to identify it is by its cryptographic hash (below), not its filename.
How many antivirus engines detected setup.exe?
Evidence-based answer
24 of 74 antivirus engines flagged setup.exe, 24 of them as outright malicious. The raw count alone does not establish safety or danger; we also weigh which engines flagged it and corroborating behavior, identity, reputation, and rule evidence. The malicious verdict comes from the complete saved evidence, not from this antivirus count by itself.
What should I do if I already installed setup.exe?
Evidence-based answer
Act quickly. 1) Disconnect the device from the internet to stop the malware communicating or spreading. 2) Run a full scan with reputable anti-malware software (such as Malwarebytes) and quarantine everything it finds. 3) Change your important passwords from a DIFFERENT, clean device — many threats log keystrokes or steal saved credentials. 4) If you bank or shop on this device, watch closely for fraud and alert your bank. 5) For a confirmed infection, the most reliable fix is to back up your personal files and reinstall the operating system for a clean start.
How do I remove setup.exe?
Evidence-based answer
To remove setup.exe: 1) restart into Safe Mode (Safe Mode with Networking if you need to download a tool) so the malware doesn't auto-start. 2) Run a full scan with reputable anti-malware software and let it quarantine or delete the detections. 3) Delete this file from the device, then empty the Recycle Bin or Trash. 4) Check your browser extensions, startup items, and scheduled tasks for anything unfamiliar. 5) Reboot and scan again to confirm it's gone. If detections keep coming back, a clean operating-system reinstall is the most dependable cure.
What kind of malware is setup.exe?
Evidence-based answer
setup.exe is classified as a trojan — malware disguised as something harmless to trick you into running it. Engines attribute it to the Yomal family. Knowing the family matters because it tells you the likely impact — data theft, remote control, file encryption, or unwanted ads — and guides the cleanup.
What is the SHA-256 hash of setup.exe?
Evidence-based answer
The SHA-256 hash of setup.exe is 0ecf9fcd79f064dd72f8cc5437346694e2265d7dee822c30332fea8db35db2ab, and its MD5 is 8c44f0b000b242a8f43d4f7a59405f80. 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.
How up to date is this analysis of setup.exe?
Evidence-based answer
This report reflects the scan run on September 19, 2026. Because a file's hash never changes, the identity of setup.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.
