Is LockAppHost.exe safe?
A verified Microsoft-signed executable received no detections from 75 engines, while its completed sandbox run exposed no offensive behavior or harmful network destination.
The executable carries a verified Microsoft Windows signature, and none of 75 antivirus engines detected it. One completed sandbox run found no offensive-only behavior, malicious child, persistence activity, or harmful contacted host, while two signer-matched files previously received clean assessments.

Before running
Run it only when it came from the developer's official site or another source you independently trust.
If you already ran it
Keep normal device protection enabled and stop if the file behaves unexpectedly.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
The executable carries a verified Microsoft Windows signature, and none of 75 antivirus engines detected it. One completed sandbox run found no offensive-only behavior, malicious child, persistence activity, or harmful contacted host, while two signer-matched files previously received clean assessments.
No antivirus engine flagged this sample: the result is 0 of 75, including no detections from 17 tier-1 engines. Its code signature verifies as Microsoft Windows and matches the curated Microsoft publisher record. A completed sandbox run produced no malicious verdict or offensive-only technique, although it did record seven ordinary ambient techniques. Reputation checks covered both observed domains and found neither in the malicious or suspicious host cache. Two prior signer-matched Microsoft executables also received clean assessments, and no packing, brand mismatch, malicious child, or external-intelligence hit counters this evidence.
What We Detected
None of 75 antivirus engines detected the executable, including 17 tier-1 engines. The file is signed by Microsoft Windows, the signature verifies correctly, and the publisher matches the curated Microsoft record. Two previous files matched by signer also received clean assessments.
Threat Behavior
One completed sandbox run produced no malicious verdict and no offensive-only MITRE technique. Seven ambient techniques were recorded, but there were no persistence indicators, written files, dropped hashes, or malicious child. The host-reputation check inspected both observed domains and found no known-malicious or suspicious entries. Static PE analysis also found no packer, high-entropy code, or brand mismatch.
What To Do Now
No remediation is indicated by the available evidence. Keep endpoint protection enabled and obtain the file through Windows or another official Microsoft-controlled update channel whenever possible.
Where this verdict could be wrong2 caveats
- signing.signerStats.totalSamples=2 is a small local history, so the trusted signature and independent engine results carry more weight than the limited signer sample count.
- The sandbox recorded seven ambient MITRE techniques, including T1027 and T1070, but no offensive-only techniques, persistence indicators, written files, or malicious sandbox verdict accompanied them.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/75 antivirus engines detected the sample.
- Verified 'Microsoft Windows' signature with signing.trustedPublisher.matched=true.
- 17 tier-1 engines reported no detection.
- behaviour.hasMaliciousSandboxVerdict=false and behaviour.offensiveCount=0.
- Both observed domains were inspected with 0 maliciousHosts and 0 suspiciousHosts.
- The local signer history contains only 2 samples.
- The sandbox recorded ambient techniques T1027 and T1070, but without offensive-only activity or a malicious verdict.
No removal action is needed based on the available evidence. Keep endpoint protection enabled and prefer an official Microsoft distribution channel if replacing or reinstalling the file.
