Don't run this file

If you already ran it, follow the steps below.

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

The file is unsigned and has no prior clean history.

Where this verdict could be wrong2 caveats
  • No dropped file is known to be malicious and 10 children inspected with no malicious verdicts
  • No community YARA rule matched and no CIRCL/MalwareBazaar hits

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.

  • Moderate concern: Checked whether it was running on a test computer.

  • Note: Read the user name of the test computer.

  • Note: Listed the programs running on the test computer.

  • Note: Talked to servers over the internet during the test run.

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

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

  • Not confirmed: A sandbox rule tagged this run as code injection, but no injected program was recorded.

  • Not confirmed: A sandbox rule tagged this run as recording keystrokes; no keylogging was confirmed.

  • Not confirmed: A sandbox rule tagged this run as weakening security settings; no setting change was recorded.

  • Not confirmed: A sandbox rule tagged this run as changing how Windows loads code; nothing confirms 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.

How do I remove Owlin.exe?
To remove Owlin.exe: 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.
