The reasoning behind this verdict

Analyst conclusion

This is the Malwarebytes setup program, carrying a valid Malwarebytes Inc signature from a trusted publisher. None of the 72 antivirus engines that checked it flagged it, and nearly 3,000 different sources have submitted it. Two community YARA rules matched, but nothing else supports them.

Where this verdict could be wrong2 caveats
  • Two community YARA rules aimed at malware patterns matched this file. Security software often contains strings that such rules key on, and no antivirus engine or sandbox run corroborates them.
  • Some community annotations tag the file as malware, but these come from automated scoring services. Other annotations note it was downloaded from the official Malwarebytes site.

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 7 questions people ask most about this file.

Is MBSetup.exe safe?
We found nothing harmful in MBSetup.exe. None of the 72 antivirus engines that checked it flag it. It has a valid digital signature from Malwarebytes Inc. Run it only if it came from the developer's own website or an official app store.
What is MBSetup.exe?
MBSetup.exe is a Windows program, about 2.8 MB. It carries no version information saying what it is or who made it. VirusTotal first saw it on Apr 7, 2026.
How many antivirus engines detected MBSetup.exe?
None of the 72 antivirus engines that checked it flag MBSetup.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.
Is MBSetup.exe digitally signed?
Yes. MBSetup.exe has a valid digital signature from Malwarebytes Inc, which shows the file hasn't been changed since that publisher signed it. Malware is sometimes signed with stolen certificates, so a signature alone isn't proof of safety.
What is the SHA-256 hash of MBSetup.exe?
The SHA-256 fingerprint of MBSetup.exe is 0b9465643cd2609856e7ebdebc34296670a2b388c2bcf6e5ee0b59430c97bf41, and its MD5 is c12892ce63fe1ece5eb0b551019f0b9a. 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 MBSetup.exe?
We found nothing harmful in MBSetup.exe, and its digital signature checks out. 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 MBSetup.exe?
This report reflects the scan on Apr 24, 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.
