Moderate evidence · Several antivirus engines agree.

Don't install this file

Delete this file from the device, then empty the Recycle Bin or Trash. Run a full-system antivirus scan.

What to do now4 steps

This file is harmful. Don't run it, and remove it.

If you haven't installed it

  1. Don't install this file. Delete it, then empty the Recycle Bin.

If you already installed it

  1. Disconnect the device from the internet, then run a full antivirus scan. Microsoft Defender Offline (Windows Security > Virus & threat protection > Scan options) also finds malware that hides while Windows runs.

  2. If you typed passwords on the device after running it, change them from another device you trust.

  3. If the scan keeps finding it, or the device still acts strangely, scan again with a second-opinion scanner from another company; if that doesn't fix it, back up your personal files and reinstall Windows.

If you already ran it, do these in order.

If you opened or installed it

Avoid banking and sign-ins on that device until it is clean. These free MalwareTips guides walk you through it.

Threat context

How trojans work

A trojan pretends to be something useful or harmless so that you run it. Once open, it does its real job in the background, 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.

Don't install it. Delete it, then empty the Recycle Bin. 4 of the 60 antivirus engines that checked it flag it, some as ValleyRAT. Antivirus engines classify it as a trojan: malware disguised as something harmless so that you run it. This exact file is also listed in MalwareBazaar, a public malware database. If you've already installed it, see the steps below.
What is this file?
e17d12a3cb758a7cd55d9e0305bc1471d30a7125cb14f3574d47f1bb91216fc4.msi is a Windows installer (MSI), about 21.8 MB. VirusTotal first saw it on Apr 27, 2026.
How many antivirus engines detected this file?
4 of the 60 antivirus engines that checked it flag e17d12a3cb758a7cd55d9e0305bc1471d30a7125cb14f3574d47f1bb91216fc4.msi, including Kaspersky and Lionic. We weigh which engines flagged it and what else the scan found, not just the count. The rating also rests on a listing of this exact file in MalwareBazaar, a public malware database, and on the other evidence.
What should I do if I already installed this file?
Act quickly. 1) Disconnect the device from the internet. 2) Run a full scan with your antivirus and let it remove what it finds. 3) Change your important passwords from another device you trust, starting with email and banking, and turn on two-step verification. 4) If you bank or shop on this device, watch your accounts and tell your bank about payments you don't recognise. 5) If the scan keeps finding it, back up your personal files and reinstall Windows.
How do I remove this file?
To remove e17d12a3cb758a7cd55d9e0305bc1471d30a7125cb14f3574d47f1bb91216fc4.msi: 1) run a full scan with your antivirus and let it remove what it finds. 2) Delete it, then empty the Recycle Bin. 3) Check Settings > Apps, your browser extensions, startup apps (Task Manager > Startup apps) and scheduled tasks for anything you don't recognise. 4) Restart and scan again. If it keeps coming back, scan from Safe Mode with Networking, or back up your files and reinstall Windows.
What kind of malware is this file?
Antivirus engines classify e17d12a3cb758a7cd55d9e0305bc1471d30a7125cb14f3574d47f1bb91216fc4.msi as a trojan: malware disguised as something harmless so that you run it. Engines attribute it to the ValleyRAT family.
Is this file digitally signed?
Yes. e17d12a3cb758a7cd55d9e0305bc1471d30a7125cb14f3574d47f1bb91216fc4.msi has a valid digital signature from MiniTool Software Limited, which shows the file hasn't been changed since that publisher signed it. Malware is sometimes signed with stolen certificates, so a signature alone isn't proof of safety.
Has this file been seen before?
Yes. This exact file is listed in MalwareBazaar, a public malware database (tracked as ValleyRAT), first listed on Apr 28, 2026. MalwareBazaar accepts uploads from anyone, including automated ones, so the listing supports the other evidence rather than proving malice on its own.
What is the SHA-256 hash of this file?
The SHA-256 fingerprint of e17d12a3cb758a7cd55d9e0305bc1471d30a7125cb14f3574d47f1bb91216fc4.msi is e17d12a3cb758a7cd55d9e0305bc1471d30a7125cb14f3574d47f1bb91216fc4, and its MD5 is 8a439d79b71266e40b932055916c0ce6. 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 this file?
This report reflects the scan on Apr 28, 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.

Member reviews and reports for this exact file hash.

Other files people checked with the same signer, and recent reports with the same rating. A matching signer does not make two files the same: only the SHA-256 fingerprint identifies a file.

All file reports
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. If you ran this file and are worried, scan your device with up-to-date security software.
