Strong evidence · A verified publisher signature, and no engine flags it.
Download Malwarebytes only from its official website. This signed installer can be run normally while your existing protection stays enabled.

Why we think so
1 point against it and 4 in its favour, checked against the scan evidence.
The reasoning behind this verdict
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.
The file carries a valid Malwarebytes Inc code signature, and the publisher is on our trusted list. It is widely distributed, with 2,946 unique submitters. Activity in the test run looked like a normal installer: writing setup logs and test files, plus a single analytics connection whose host showed no known-bad reputation. Two community YARA rules matched, but they are a weak lead given the verified signature and the absence of any detection.
What We Detected
None of the 72 antivirus engines that checked it flagged this installer. It carries a valid code signature from Malwarebytes Inc, a trusted publisher, and has been submitted by nearly 3,000 different sources. A previously analysed installer from the same signer also showed no problems. Two community YARA rules aimed at malware patterns matched, but no engine or sandbox result supports them.
Threat Behavior
The sandbox runs showed setup activity typical of an installer. The program wrote setup logs and Malwarebytes test files to program and driver folders. It also made one analytics connection, and that host has no known-bad reputation. No injection into another process was recorded, and no high-risk techniques were observed.
What To Do Now
If you downloaded this from the official Malwarebytes website, it is appropriate to run it. Keep your existing security software enabled during installation.
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.
- Valid code signature from Malwarebytes Inc, a trusted publisher
- No detections from any of the 76 antivirus engines
- Widely distributed, with nearly 3,000 unique submitters
- Behaviour matched a normal software installer
- Two community YARA rules matched malware-style patterns, though nothing else corroborates them.

VirusTotal's sandbox summary maps this run to MITRE T1055 (Process Injection), but no injected process of the sample's own was recorded (the analysis VM's own WMI adapter, crash handlers and Chrome updater are not counted). VirusTotal maps T1055 on about half of all files no engine flags, so the mapping alone is not evidence of injection.

Section entropy & packers
No high-entropy executable section or known packer signature was detected. Data and resource sections can still have high entropy without indicating packed code.
How widely this file has been seen
Widely seen in the wild for a long time. High prior this is legitimate; isolated detections on common-old files are usually false positives.
