Threat context

How worms spread

A worm copies itself from one computer to the next — across your network, through shared drives, or on USB sticks — without you doing anything. One infected machine can quickly reach every device around it.

Bottom line:A single infected machine can rapidly compromise every device it can reach.

8 evidence-based answers
Is this file a virus?
Evidence-based answer
Yes — this file is malicious. Do not open it. Delete this file from the device, then empty the Recycle Bin or Trash. 29 of 37 antivirus engines flag it (family: autorun). It behaves as a worm, which spreads itself to other machines. If you've already opened it, see the removal and recovery steps below.
What is this file?
Evidence-based answer
this file is a file, about 402 KB. Our analysis identifies it as malicious (family: autorun) — a worm, which spreads itself to other machines. 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
29 of 37 antivirus engines flagged this file, 29 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 opened 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 this file: 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
this file is classified as a worm, which spreads itself to other machines. Engines attribute it to the autorun 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 this file?
Evidence-based answer
The SHA-256 hash of this file is f7658dce18999a70da5ebacd1abec048694daaecec7e3153d2dc294b49b7c42c, and its MD5 is 7e93d5f4e36c8b0ad2af6f6c2aadd0f0. 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 September 6, 2026. Because a file's hash never changes, the identity of this file 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.
