What to do now4 steps

Some signs point to a problem, but nothing confirms it is harmful. Treat it with caution.

What to do

  1. Don't run it unless you're sure where it came from.

  2. Check where you got it: an unexpected attachment, a link someone sent you or a re-upload is a red flag.

  3. If you can't confirm where it came from, delete it. If you need the program, download it again from the publisher's own website.

If you already ran it

  1. Stop using it, run a full scan with your antivirus and watch for unexpected behavior or security alerts.

The reasoning behind this verdict

Analyst conclusion

14 of the 71 antivirus engines that checked it flag this unsigned, UPX-packed executable, including three major antivirus engines, but none name a malware family. In sandbox runs it launched hidden PowerShell windows to check versions and unpack a local archive, with no network contacts or injection recorded. The signals are mixed, so caution is warranted.

Where this verdict could be wrong2 caveats
  • The detections are all generic or machine-learning labels with no named malware family, and the observed PowerShell commands only check versions and unpack a local archive, which supports a false positive on a niche utility.
  • Three major antivirus engines still flag it, and an unsigned UPX-packed executable that runs hidden PowerShell is also the shape of a loader.

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: Checked whether it was running on a test computer.

  • Note: Listed the programs running on the test computer.

  • Note: Read basic details of the test computer, such as its Windows version.

  • Note: Loaded extra code modules while running.

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.

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.

What should I do if I already ran GenPatcher.exe?
No infection is confirmed: the rating is a caution, not a malware finding. 1) Check where it came from. If you can't confirm the source, delete it. 2) Run a full scan with your security software. 3) If the scan finds something, follow its removal steps and change passwords you typed on the device since then.
What is the SHA-256 hash of GenPatcher.exe?
The SHA-256 fingerprint of GenPatcher.exe is 9c940f59503e099b9eead096d2092608896e9553075652e71653bfb798b7c0a1, and its MD5 is 92014ec670d77862ed008b20f0a82fdc. Two files with the same SHA-256 are identical, so use it to check you have exactly this file, not just one with the same name.
How up to date is this analysis of GenPatcher.exe?
This report reflects the scan on Oct 19, 2026. A file's fingerprint never changes, but antivirus engines keep learning, so a rating can change later. To get a newer result, scan the file again: we refresh the antivirus results when the saved ones are out of date.
