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

The reasoning behind this verdict

Analyst conclusion

The file is unsigned, submitted only once, and shows no sandbox or network malice indicators.

Where this verdict could be wrong2 caveats
  • No sandbox returned a malicious verdict and no contacted malicious hosts — runtime shows no a control server or persistence indicators.
  • If the major detections are all generic ML/HEUR labels, the family consensus could be overstated; however three major antivirus engines explicitly name MalwareX/Kryptik variants.

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 it did in our test

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.
