What this file does

Observed actions and their security significance

  • High concern: Used removable-media replication behaviour that can spread files between devices.

  • High concern: Created or modified a system service, which can keep code running.

  • Note: Collects details about your system.

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.

8 evidence-based answers
Is setup.msi malware?
Evidence-based answer
Yes — setup.msi is malicious. Do not install it. Delete this file from the device, then empty the Recycle Bin or Trash. 21 of 76 antivirus engines flag it (family: Runner/Cobalt). 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.msi?
Evidence-based answer
setup.msi is a software installer, about 5.3 MB. Our analysis identifies it as malicious (family: Runner/Cobalt) — 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.msi?
Evidence-based answer
21 of 76 antivirus engines flagged setup.msi, 21 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.
I already downloaded and installed setup.msi — what should I do?
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.msi?
Evidence-based answer
To remove setup.msi: 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.msi?
Evidence-based answer
setup.msi is classified as a trojan — malware disguised as something harmless to trick you into running it. Engines attribute it to the Runner/Cobalt 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.msi?
Evidence-based answer
The SHA-256 hash of setup.msi is 1f3f67b696ba113c3b51842381e060dab420df76f76b015f5cb64b20c383c003, and its MD5 is 31c4c4c1891463d6e7eb816cb67caf5e. 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.msi?
Evidence-based answer
This report reflects the scan run on July 2, 2026. Because a file's hash never changes, the identity of setup.msi 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.
