What this file does

Observed actions and their security significance

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

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

  • High concern: Attempted to impair or bypass security controls.

  • 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: Checked the environment for virtualisation or analysis tools.

  • 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 remote-access malware works

This opens a secret 'back door' into your computer. Once it's running, an attacker can control your PC from anywhere — see your screen, read your files, switch on your webcam, install more malware, or use your machine to attack others.

Bottom line:It's built to stay hidden and keep that connection open for as long as possible.

What to do now

This file is dangerous. Treat it as harmful and remove it.

  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

    If you typed any passwords while it was open, change them from a device you trust.

  4. Recovery step 04

    Download a fresh installer from the developer's official site or an official app store.

9 evidence-based answers
Is this file a virus?
Evidence-based answer
Yes — e17d12a3cb758a7cd55d9e0305bc1471d30a7125cb14f3574d47f1bb91216fc4.msi is malicious. Do not install it. Delete this file from the device, then empty the Recycle Bin or Trash. 4 of 75 antivirus engines flag it (family: ValleyRAT). It behaves as a backdoor/remote-access trojan that lets an attacker control the device remotely. If you've already installed it, see the removal and recovery steps below.
What is this file?
Evidence-based answer
e17d12a3cb758a7cd55d9e0305bc1471d30a7125cb14f3574d47f1bb91216fc4.msi is a software installer, about 20.7 MB. Our analysis identifies it as malicious (family: ValleyRAT) — a backdoor/remote-access trojan that lets an attacker control the device remotely. 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 this file?
Evidence-based answer
4 of 75 antivirus engines flagged e17d12a3cb758a7cd55d9e0305bc1471d30a7125cb14f3574d47f1bb91216fc4.msi, 4 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 this file?
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 this file?
Evidence-based answer
To remove e17d12a3cb758a7cd55d9e0305bc1471d30a7125cb14f3574d47f1bb91216fc4.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 this file?
Evidence-based answer
e17d12a3cb758a7cd55d9e0305bc1471d30a7125cb14f3574d47f1bb91216fc4.msi is classified as a backdoor/remote-access trojan that lets an attacker control the device remotely. Engines attribute it to the ValleyRAT 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.
Is this file digitally signed?
Evidence-based answer
Yes — e17d12a3cb758a7cd55d9e0305bc1471d30a7125cb14f3574d47f1bb91216fc4.msi carries a valid digital signature from MiniTool Software Limited, 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.
What is the SHA-256 hash of this file?
Evidence-based answer
The SHA-256 hash of e17d12a3cb758a7cd55d9e0305bc1471d30a7125cb14f3574d47f1bb91216fc4.msi is e17d12a3cb758a7cd55d9e0305bc1471d30a7125cb14f3574d47f1bb91216fc4, and its MD5 is 8a439d79b71266e40b932055916c0ce6. 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 this file?
Evidence-based answer
This report reflects the scan run on April 28, 2026. Because a file's hash never changes, the identity of e17d12a3cb758a7cd55d9e0305bc1471d30a7125cb14f3574d47f1bb91216fc4.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.
