Why we think so
5 points against it and 5 in its favour, checked against the scan evidence.
The reasoning behind this verdict
The combined sandbox verdict was clean, with no injected processes, no contacted domains and no dropped files. The publisher's small sample history contains no malicious entries.
None of the 63 antivirus engines that checked it flagged this installer, and every one of the 18 major antivirus engines that analysed it returned a clean result. The file carries a valid signature from Learning Machines Inc, and our history for that publisher covers seven samples with none rated malicious. Sandbox analysis produced a clean combined result across the runs, with no injected process, no dropped files and no outbound domains recorded. The only sandbox mapping of note was a process-injection label with no named target, which is a common artefact of installer setup routines rather than evidence of injection. The file was submitted by 32 distinct sources within a day of first appearing, and files sharing this publisher signature have previously been rated clean three times out of five. The lack of a completed host-reputation check and the absence of an inside look at the installer payload are coverage gaps, not findings against the file.
What We Detected
The file is a Windows Installer package with a valid digital signature naming Learning Machines Inc. No engine flagged it, including all 18 major antivirus engines that returned a result, and there were no suspicious or potentially unwanted detections either. Microsoft, Kaspersky, ESET-NOD32, BitDefender, Fortinet, Avira, Avast, G Data and Ikarus all reported the file as clean.
Publisher And History
The publisher's signature verified successfully and our records hold seven earlier samples under the same identity, five rated clean and none rated malicious. That is a short history, and the publisher is not on our curated list of established vendors, so the signature supports the file without being decisive on its own. Four other installers and launchers from this publisher appeared in earlier analyses; three were rated clean and two were rated cautiously, which is why confidence stays moderate.
Threat Behavior
The combined sandbox verdict was clean. The installer ran through the standard Windows installer service, wrote temporary installer files and font cache entries, registered a root certificate entry and created the usual installer program markers — all routine installation activity. No processes were injected, no files were dropped that carry a verdict, no persistence was established outside the installation itself and no network destinations were contacted.
What To Do Now
The evidence does not point to malware, but the file arrived under a random string rather than a product-named installer and we could not inspect the package contents internally. If you did not expect this installer, confirm with the sender or download it again from the vendor's own site before running it. Keep your antivirus protection enabled, and let it scan the installed program after setup completes.
Where this verdict could be wrong4 caveats
- Two earlier installers carrying the same publisher signature were rated cautiously rather than clean by our analysis, so this publisher's recent output has not always been judged benign.
- The publisher is not on our curated trusted list and we only hold a short history of seven samples, which limits how much weight its signature carries on its own.
- The reputation check on hosts the installer might contact was not completed, so no host-level verification result is available for this file.
- Nobody has looked inside this installer's payload: the containers and scripts it carries were not unpacked, so the internal contents were not examined.
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 digital signature from Learning Machines Inc that passed verification.
- None of the 63 antivirus engines that checked it flagged the file, including all 18 major antivirus engines that returned a result.
- The combined sandbox verdict was clean with no injected processes and no contacted domains.
- The publisher's record shows no malicious samples among the seven we have seen.
- Thirty-two distinct sources submitted the file within a day of it first appearing, which is consistent with a normal software release.
- The publisher is not on our curated trusted-vendor list and we hold only a short history of samples under that name.
- Two earlier installers carrying the same publisher signature were rated cautiously by our analysis rather than clean.
- The file arrived under a random identifier rather than a product-named installer, so what it actually installs cannot be judged from the file name.
- The installer's internal contents were not unpacked or examined, so what it deploys after setup was not reviewed here.
- No completed reputation result is available for destinations the installer might reach.
