Don't use this component

If you already used 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 used it

  1. Don't use this component. Let your antivirus remove this component, then repair or reinstall the program it belongs to from its official website. Don't delete or replace the file by hand.

If you already used 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

Multiple major antivirus engines including Microsoft, Symantec and TrendMicro detect the sample as Zusy/Kepavll. The file is unsigned, packed, and exhibits offensive MITRE techniques and T1620.

Where this verdict could be wrong2 caveats
  • similarHashes returned two prior safe verdicts on import-table fingerprint matches (signerCoMatch=false) — framework collision possible, not strong counter-signal.
  • contactedHosts is null; no complete host-reputation result available.

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: Unpacked hidden content while it ran.

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

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

  • Note: Deleted files or logs during the test run (installers often clean up after themselves).

  • 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 contacting a server, but no contacted host was recorded.

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

  • Not confirmed: A sandbox rule tagged this run as loading code in memory; nothing confirms it.

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 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.
