Where this verdict could be wrong1 caveat
  • If this hash is a polymorphic-collision with a legitimate build, the MB label would be misleading — but MB curation makes this extremely rare.

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

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

  • High concern: Manipulated how the operating system loads code, which can redirect execution.

  • High concern: Installs itself to survive restarts (persistence).

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

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

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.

10 evidence-based answers
Is hamachi.msi a virus?
Evidence-based answer
Yes — hamachi.msi is malicious. Do not install it. Delete this file from the device, then empty the Recycle Bin or Trash. 0 of 75 antivirus engines flag it (family: confirmed malware). It behaves as a trojan — malware disguised as something harmless to trick you into running it. It's also a confirmed malware sample catalogued by the abuse.ch threat-intelligence community. If you've already installed it, see the removal and recovery steps below.
What is hamachi.msi?
Evidence-based answer
hamachi.msi is a software installer, about 13.9 MB. Our analysis identifies it as malicious (family: confirmed malware) — 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 hamachi.msi?
Evidence-based answer
None — 0 of 75 antivirus engines flagged hamachi.msi. That's reassuring, though it is not proof that a file is safe, so we also weigh its behaviour, identity, and reputation.
What should I do if I already installed hamachi.msi?
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 hamachi.msi?
Evidence-based answer
To remove hamachi.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 hamachi.msi?
Evidence-based answer
hamachi.msi is classified as a trojan — malware disguised as something harmless to trick you into running it. Engines attribute it to the confirmed malware 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 hamachi.msi digitally signed?
Evidence-based answer
Yes — hamachi.msi carries a valid digital signature from GoTo Technologies USA, 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.
Has hamachi.msi been seen before?
Evidence-based answer
Yes — this exact file is a known, catalogued malware sample in the abuse.ch MalwareBazaar threat-intelligence feed, first seen on June 13, 2026. A confirmed listing there is strong, independent evidence that the file is malicious.
What is the SHA-256 hash of hamachi.msi?
Evidence-based answer
The SHA-256 hash of hamachi.msi is d429afe52323c2b856c0ce1b9feb69176ca17a1b4ce9e2e37c5b618307839715, and its MD5 is 30b78eb9da15a84d58f14297c00a7456. 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 hamachi.msi?
Evidence-based answer
This report reflects the scan run on August 19, 2026. Because a file's hash never changes, the identity of hamachi.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.
