Why we think so
0 points against it and 5 in its favour, checked against the scan evidence.
The reasoning behind this verdict
None of the 71 antivirus engines that checked it flagged this installer, and it carries a verified signature from Malwarebytes Inc, a publisher on our trusted list. One sandbox run returned malicious while another returned clean, with no injection target recorded, which fits normal installer behaviour.
The file is validly signed by Malwarebytes Inc and matches our curated trusted-publisher list. Across six sandbox runs, one returned a malicious verdict and another returned clean; no process injection target was recorded and only techniques common in legitimate installers were mapped, such as writing test files and setting Malwarebytes registry keys. Its network contacts, an analytics service and an Amazon certificate host, showed no known-malicious or suspicious reputation in our host check. A prior file from the same signer was also judged clean.
What We Detected
None of the 71 antivirus engines that checked it flagged this Win32 installer. It carries a verified code signature from Malwarebytes Inc, a trusted publisher, and has been submitted by 1,778 distinct sources in its first ten days. Reference databases and community rule sets returned no hits.
Threat Behavior
Six sandbox runs observed the installer. One run returned malicious and another returned clean. The activity seen — writing Malwarebytes test files, setting Malwarebytes registry keys, contacting an analytics endpoint and an Amazon certificate host — matches a security-product setup program. No injection into another process was recorded, and the five contacted hosts we checked carry no malicious or suspicious reputation.
What To Do Now
If you downloaded this from the official Malwarebytes site, it can be run normally. Keep your existing antivirus enabled during installation.
Where this verdict could be wrong2 caveats
- One sandbox run returned a malicious verdict, but another run returned clean and no injection target or other hard runtime artefact was recorded.
- A community annotation from an automated analysis feed gave a high threat score, but it names no family and no engine supports 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.
