The reasoning behind this verdict

Analyst conclusion

No engine detected anything in this 52 KB executable, and the combined sandbox result was clean with no injection, no dropped files and no unusual techniques. It has been submitted by 100 different sources since it first appeared on Jun 7, 2021, and the only network contacts recorded were ordinary Microsoft data addressed by the analysis machine itself. Nothing hostile appears in the file.

Where this verdict could be wrong2 caveats
  • The file carries no digital signature, so its origin cannot be confirmed from the binary itself; the clean result rests on engine agreement, sandbox runs and its long submission history.
  • No similarity comparison with previously reviewed files was available for this hash, so there is no historical verdict trail to reinforce the result.

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 ClamWin.exe safe?
We found nothing harmful in ClamWin.exe. None of the 70 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 ClamWin.exe?
ClamWin.exe is a Windows program, about 53.2 kB. Its version information says it is “ClamWin Antivirus”. Version information is written by whoever built the file, so it is a claim, not proof of who made it. VirusTotal first saw it on Jun 7, 2021.
How many antivirus engines detected ClamWin.exe?
None of the 70 antivirus engines that checked it flag ClamWin.exe. 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 ClamWin.exe?
The SHA-256 fingerprint of ClamWin.exe is cf3f26cd319dc1e58eee91c752c02a737849fa6d28dd11f7c297ac72152ece8d, and its MD5 is 191551178d0f362f463ffd3c4462afaf. 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 ClamWin.exe?
We found nothing harmful in ClamWin.exe. 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 ClamWin.exe?
This report reflects the scan on Nov 7, 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.
