Verdict Safe
Is dot
Microsoft-signed .NET Framework 4.0 installer with zero engine detections and strong historical signer reputation.
Read the whole reasonShow less
Strong evidence · A verified publisher signature, and no engine flags it.
Treat as a legitimate Microsoft .NET Framework 4.0 installer; no further security action needed.
Good practice2 tips
We found nothing harmful in this file.
Install it only if it came from the developer's own website or an official app store.
Keep your antivirus and Windows updates switched on.
No scanner can promise a file is 100% safe.

Chapter 02
Why we think so
0 points against it and 4 in its favour, checked against the scan evidence.
The reasoning behind this verdict
Zero of the 71 antivirus engines that checked it flagged the file. It is signed by Microsoft Corporation, matches a trusted-publisher record, and shows 4 of 5 similar hashes previously rated safe under the same signer. The file is a common, old .NET redistributable installer.
The complete absence of malicious detections across 75 engines, including 17 major antivirus engines, combined with verified Microsoft code-signing, places the sample firmly in the benign-signed-installer pattern. Historical signer data shows 8/9 prior samples rated safe, and four of five similar-hash matches under the same signer also returned safe verdicts with the same reason code. Prevalence data (widely seen and long established, nearly 90 k submissions) further supports legitimate commodity software. Sandbox artefacts that triggered rule-based rules are consistent with a .NET bootstrapper touching the Windows password store and system services during installation; no malicious files it created or sandbox verdicts were recorded.
What We Detected
75-engine scan returned zero malicious or suspicious labels. The executable is signed by Microsoft Corporation with a verified certificate issued 19 March 2010. Our trusted-publisher list explicitly includes Microsoft, and the file matches the expected .NET Framework 4.0 redistributable (dotNetFx40_Full_setup.exe).
Threat Behavior
One sandbox recorded typical installer behaviour: extraction of bitmap resources, creation of temporary files, and service-process interaction. Four MITRE techniques flagged by rules (T1005, T1055, T1543.003, T1562.001) map to expected bootstrapper actions rather than attacker tradecraft. no complete contacted-host reputation result was available, IPs, or programs it started were observed.
What To Do Now
The file can be executed or distributed without elevated concern. Keep Windows Defender and other security software enabled; no additional action is required.
Where this verdict could be wrong2 caveats
- The signer-history record shows 1/9 malicious historical sample for Microsoft Corporation — single outlier against 8/9 safe.
- triggeredHeuristics fired 'one of our behaviour rules' and 'one of our behaviour rules' on the Windows password store and svchost activity — sandbox artefacts from legitimate .NET installer bootstrapper.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Microsoft Corporation code signature verified
- 0/71 engines flagged malicious
- widely seen and long established prevalence with nearly 90 k submissions
- 4 of 5 similar signer-matched hashes previously rated safe

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.
