Strong evidence · Two or more major antivirus engines agree.

Don't run this file

Do not run this file; delete it. If it was already executed, run a full scan and remove any software you did not knowingly install.

What to do now4 steps

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

If you haven't run it

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

If you already ran 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.

The reasoning behind this verdict

Analyst conclusion

45 of the 67 antivirus engines that checked it flag this unsigned executable, including 11 major antivirus engines. Microsoft and Kaspersky name the OffLoader downloader family, and ESET and Ikarus describe an NSIS-based trojan downloader. Its sandbox traces match how OffLoader installers stage their files.

Where this verdict could be wrong2 caveats
  • The recorded sandbox verdict was clean and no network contacts or high-risk techniques were observed, so the download stage may not have triggered during analysis.
  • Malwarebytes labels it riskware rather than a trojan, and OffLoader installers sit close to aggressive bundleware.

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 the test run showed

What the file did on a test computer

Confirmed in the test run

  • Moderate concern: Contains packed or scrambled code that is harder to inspect (common in installers too).

  • Moderate concern: Ran commands or a script on the test computer.

  • Note: Read basic details of the test computer, such as its Windows version.

  • Note: Looked through folders on the test computer (most installers do this).

  • Note: Loaded extra code modules while running.

Sandbox labels we could not confirm (common in safe files too)

  • Not confirmed: A sandbox rule tagged this run as contacting a server, but no contacted host was recorded.

  • Not confirmed: A sandbox rule tagged this run as setting up auto-start; no auto-start entry was recorded.

This file was run on a test computer (a sandbox), not on yours. Labels we could not confirm are listed so you can see them, but they are not treated as evidence against the file.

Threat context

How downloaders work

This file is a delivery vehicle. On its own it can look small and harmless, but its job is to fetch and install the real payload, often a password stealer, ransomware or a bot, from a server the attacker controls.

Bottom line:Because the dangerous part arrives later, early scans can look cleaner than the threat really is.
