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.

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: 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.

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

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 changing how Windows loads code; nothing confirms it.

Threat context

How remote-access malware works

This opens a secret way into the computer. Once it runs, an attacker can control the PC from anywhere: see the screen, read files, install more malware or use the machine to attack others.

Bottom line:It is built to stay hidden and keep that connection open for as long as possible.
