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. From another device you trust, change the passwords of your important accounts (email and banking first) and turn on two-step verification.

  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.

The reasoning behind this verdict

Analyst conclusion

Four major antivirus engines (Avast, AVG, Kaspersky, Fortinet) identify this unsigned executable as Python:Discord-H, a known Discord token-stealing infostealer. The antivirus analysis reveals reconnaissance techniques (process discovery, file enumeration, command execution) consistent with credential-harvesting malware. No sandbox execution data is available, but the convergence of major family naming across independent vendors is a strong malicious signal.

Where this verdict could be wrong4 caveats
  • tier1FamilyConsensus.strong=false (only 2 engines agreeing, threshold ≥3) — technically does not meet 'strong consensus' bar, though 4 malicious detections from major antivirus engines is still substantial.
  • No sandbox execution data available; behaviour analysis relies on static MITRE technique extraction rather than observed activity in the test run. Sandbox verdicts could confirm or refute the static assessment.
  • High PE entropy (7.999) and overlay tag could indicate legitimate compression (e.g., PyInstaller bundling Python runtime) rather than evasion, though this does not explain major family consensus.
  • No external YARA/CIRCL hits; community researcher corroboration is absent. However, 'disco' family (Discord token stealer) is well-known; absence of YARA hits may reflect rule-coverage gaps rather than true absence of malware.

These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.

Threat context

How password stealers work

A password stealer runs quietly in the background and copies your private data, such as saved passwords, browser cookies, autofill details and crypto wallets, then sends it to criminals. You usually won't notice anything.

Bottom line:Stolen logins are used to break into your accounts or sold in bulk, so change passwords from another device.
