Is patch.exe safe?

Verdict
Malicious

Thirty-nine of 74 engines flagged this unsigned executable, including nine tier-1 detections, while runtime evidence mapped activity to process injection technique T1055.

The evidence strongly indicates a Windows trojan associated most often with Pomal or Yogi labels. Microsoft and Ikarus identify Pomal, several other established engines identify Yogi, and the sandbox evidence maps activity to process injection and includes LSASS-related process activity.

Do not run this file

Quarantine or delete the file without running it, and keep endpoint protection enabled. If it already executed, isolate the system, perform a full scan, and investigate possible process injection and credential exposure.

The reasoning behind this verdict

This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.

97%Confidence
Very high
Analyst conclusion

The evidence strongly indicates a Windows trojan associated most often with Pomal or Yogi labels. Microsoft and Ikarus identify Pomal, several other established engines identify Yogi, and the sandbox evidence maps activity to process injection and includes LSASS-related process activity.

Where this verdict could be wrong4 caveats
  • engines.tier1FamilyConsensus.strong=false, and only two tier-1 votes agree specifically on Pomal, so the exact family name is less certain than the malware finding.
  • behaviour.hasMaliciousSandboxVerdict=false, and the completed sandbox recorded no contacted domains, IPs, or URLs.
  • externalIntel.yaraify.ruleCount=0, externalIntel.circl.hit=false, and externalIntel.malwareBazaar.hit=false; these may reflect coverage gaps rather than exoneration.
  • peAnalysis.highEntropyCode=false and peAnalysis.likelyPacked=false, providing no packing-based corroboration.

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

Recommended action

Quarantine or delete the file without running it, and keep endpoint protection enabled. If it already executed, isolate the system, perform a full scan, and investigate possible process injection and credential exposure.

What this file does

Observed actions and their security significance

  • High concern: Injected code into another process, a technique that can conceal execution.

  • Moderate concern: Contained obfuscated or packed code that makes inspection harder.

  • Moderate concern: Scans through your files and folders.

  • Moderate concern: Checked the environment for virtualisation or analysis tools.

  • Note: Reads your Windows user-account details.

  • Note: Collects details about your system.

  • Note: Loads extra code modules while running.

These are observed capabilities from an isolated analysis. A technique does not prove malicious intent on its own, and the file never ran on your device.

Threat context

How trojans work

A trojan disguises itself as something useful or harmless to trick you into running it. Once open, it does its real job in the background — anything 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.

What to do now

This file is dangerous. Treat it as harmful and remove it.

  1. Recovery step 01

    Don't run this file. Delete this file from the device, then empty the Recycle Bin or Trash.

  2. Recovery step 02

    If you already ran it, disconnect from the internet and start with a full antivirus scan or Microsoft Defender Offline scan. If compromise is suspected or the problem persists, use a reputable second-opinion scanner and follow incident-recovery or clean-reinstall guidance.

  3. Recovery step 03

    If you typed any passwords while it was open, change them from a device you trust.

  4. Recovery step 04

    Get a fresh copy from the developer's official site or an official app store.

8 evidence-based answers
Is patch.exe malware?
Evidence-based answer
Yes — patch.exe is malicious. Do not run it. Delete this file from the device, then empty the Recycle Bin or Trash. 39 of 74 antivirus engines flag it (family: Pomal). It behaves as a trojan — malware disguised as something harmless to trick you into running it. If you've already run it, see the removal and recovery steps below.
What is patch.exe?
Evidence-based answer
patch.exe is a Windows executable program, about 418 KB. Our analysis identifies it as malicious (family: Pomal) — a trojan — malware disguised as something harmless to trick you into running it. Because a file's name and icon can be faked, the safest way to identify it is by its cryptographic hash (below), not its filename.
How many antivirus engines detected patch.exe?
Evidence-based answer
39 of 74 antivirus engines flagged patch.exe, 39 of them as outright malicious. The raw count alone does not establish safety or danger; we also weigh which engines flagged it and corroborating behavior, identity, reputation, and rule evidence. The malicious verdict comes from the complete saved evidence, not from this antivirus count by itself.
I already downloaded and ran patch.exe — what should I do?
Evidence-based answer
Act quickly. 1) Disconnect the device from the internet to stop the malware communicating or spreading. 2) Run a full scan with reputable anti-malware software (such as Malwarebytes) and quarantine everything it finds. 3) Change your important passwords from a DIFFERENT, clean device — many threats log keystrokes or steal saved credentials. 4) If you bank or shop on this device, watch closely for fraud and alert your bank. 5) For a confirmed infection, the most reliable fix is to back up your personal files and reinstall the operating system for a clean start.
How do I remove patch.exe?
Evidence-based answer
To remove patch.exe: 1) restart into Safe Mode (Safe Mode with Networking if you need to download a tool) so the malware doesn't auto-start. 2) Run a full scan with reputable anti-malware software and let it quarantine or delete the detections. 3) Delete this file from the device, then empty the Recycle Bin or Trash. 4) Check your browser extensions, startup items, and scheduled tasks for anything unfamiliar. 5) Reboot and scan again to confirm it's gone. If detections keep coming back, a clean operating-system reinstall is the most dependable cure.
What kind of malware is patch.exe?
Evidence-based answer
patch.exe is classified as a trojan — malware disguised as something harmless to trick you into running it. Engines attribute it to the Pomal family. Knowing the family matters because it tells you the likely impact — data theft, remote control, file encryption, or unwanted ads — and guides the cleanup.
What is the SHA-256 hash of patch.exe?
Evidence-based answer
The SHA-256 hash of patch.exe is a6b38c1ceab1dc64a71f2e1e1499ecad4a2da577cf0351e2394773c46604c144, and its MD5 is 778c989a3f72a1896f4957ea082fb856. This hash is the file's unique fingerprint — two files with the same SHA-256 are identical. Use it to confirm you're looking at exactly this file (not just one with the same name) when comparing against antivirus databases or a download's published checksum.
How up to date is this analysis of patch.exe?
Evidence-based answer
This report reflects the scan run on September 19, 2026. Because a file's hash never changes, the identity of patch.exe is fixed — but antivirus coverage improves over time, so a file that looks clean today can pick up detections later (and vice-versa). If you need the latest picture, MalwareTips staff can re-run the analysis from scratch.
