The reasoning behind this verdict

Analyst conclusion

None of the 71 antivirus engines that checked it flagged this file, including all 17 major antivirus engines that returned results. It has been seen by more than 2,600 independent submitters since late 2022. The sandbox run ended clean, and its network activity was a GitHub update check. Two community YARA rules matched, but nothing else supports them.

Where this verdict could be wrong3 caveats
  • Two malware-specific community YARA rules matched, including one written for the Jupyter/Solarmarker infostealer, though no antivirus engine agrees.
  • The sandbox mapped process injection into a Windows WMI helper, though the targets look like the analysis machine's own background activity.
  • The file is unsigned, so no publisher identity backs it.

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

Questions & answers

Short answers to the 6 questions people ask most about this file.

Is FrostyFix.dll safe?
We found nothing harmful in FrostyFix.dll. None of the 71 antivirus engines that checked it flag it. Run it only if it came from the developer's own website or an official app store.
What is FrostyFix.dll?
FrostyFix.dll is a Windows program, about 1.7 MB. It carries no version information saying what it is or who made it. VirusTotal first saw it on Dec 16, 2022.
How many antivirus engines detected FrostyFix.dll?
None of the 71 antivirus engines that checked it flag FrostyFix.dll. That is a good sign, but not proof, so we also weigh who made it, how widely it is used and what it did in a test run.
What is the SHA-256 hash of FrostyFix.dll?
The SHA-256 fingerprint of FrostyFix.dll is c9eea9bc435b5f5d93f45cf5b378ca6b15bd6da696de81d5fbc38410268ee9ee, and its MD5 is a2c5f2c7b36132c763a8eadabd6a8088. 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.
Is it safe to run FrostyFix.dll?
We found nothing harmful in FrostyFix.dll. The main caveat is where you got it: attackers sometimes spread malware under the name of real software, so get it from the official website. If your own antivirus warns about it, check the source before you ignore the warning.
How up to date is this analysis of FrostyFix.dll?
This report reflects the scan on Oct 17, 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.
