Recommended next actions

01

Before running

Do not run it until the source and publisher can be verified independently.

02

If you already ran it

Stop using it, scan the device, and watch for unexpected behavior or security alerts. Get a fresh copy from the developer's official site or an official app store.

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 an input-capture technique that can record credentials or keystrokes.

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

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

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.

    If you're still unsure, scan it again in a day or two — detections often catch up on newer files.

Safety FAQ

Direct answers grounded in the saved verdict and evidence in this report.

8 evidence-based answers
Is arnis-windows.exe safe, or is it malware?
Evidence-based answer
arnis-windows.exe is suspicious — treat it as unsafe until you're sure. 1 of 75 antivirus engines flag it; that detection signal contributes to the cautious verdict. Don't run it unless you fully trust where it came from. Get a fresh copy from the developer's official site or an official app store.
What is arnis-windows.exe?
Evidence-based answer
arnis-windows.exe is a Windows executable program, about 39.3 MB. We identify a file by its cryptographic hash rather than its name, because the same filename can be reused by completely different files — the hash below is the reliable fingerprint.
How many antivirus engines detected arnis-windows.exe?
Evidence-based answer
1 of 75 antivirus engines flagged arnis-windows.exe, 1 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.
What should I do if I already ran arnis-windows.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 arnis-windows.exe?
Evidence-based answer
To remove arnis-windows.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.
Is arnis-windows.exe digitally signed?
Evidence-based answer
arnis-windows.exe claims a signer of Arnis, but the signature is not verified — an unverified or broken signature can be forged, so it should not be trusted as proof of who made the file.
What is the SHA-256 hash of arnis-windows.exe?
Evidence-based answer
The SHA-256 hash of arnis-windows.exe is 2bbfa21cba3d69207a26a39350fd9fd74b8d4562f422fc4dd977d993d570e918, and its MD5 is 432ab0e0ba35ca6f5fd2dac727723c76. 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 arnis-windows.exe?
Evidence-based answer
This report reflects the scan run on May 19, 2026. Because a file's hash never changes, the identity of arnis-windows.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.
