Is YIHomePCClientIntl_download_1.0.0.2.exe safe?
Single low-trust detection on a 9-year-old signed installer with no tier-1 flags or malicious runtime signals.
Only one low-trust engine flagged the file; all 17 tier-1 engines returned clean. The sample is a signed NSIS installer from Shanghai Xiaoyi Technology Co. that has been submitted 502 times since 2017 with no malicious sandbox or child-file findings.

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.
Intelligence
The saved assessment, checked against the scan evidence and recorded coverage.
The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
Only one low-trust engine flagged the file; all 17 tier-1 engines returned clean. The sample is a signed NSIS installer from Shanghai Xiaoyi Technology Co. that has been submitted 502 times since 2017 with no malicious sandbox or child-file findings.
The engine profile shows a single low-trust detection against 70 clean results and zero tier-1 malicious flags, a pattern strongly associated with false positives. The file is signed and verified, carries a common-old prevalence classification, and produced no malicious sandbox verdict or malicious dropped children. The one heuristic that fired (DirectIpC2) explicitly notes that direct-IP traffic can occur in legitimate installers, so it does not override the clean signals.
What We Detected
75 engines scanned the sample; only VBA32 (low-trust tier) returned a generic 'Trojan.Downloader.gen' label. All 17 tier-1 engines remained silent. The executable is signed by Shanghai Xiaoyi Technology Co. and packaged with NSIS; no brand mismatch was found.
Threat Behavior
One sandbox run recorded ambient system queries and direct-IP connections to Google and Akamai infrastructure, but no malicious verdict was issued. Ten dropped children were inspected and none carried malicious verdicts. No persistence mechanisms or registry modifications were observed.
What To Do Now
The file can be treated as a legitimate Yi Home PC client installer. Keep endpoint protection enabled; no additional action is required.
Where this verdict could be wrong1 caveat
- signerStats.found=false — no historical samples for this signer, so reputation cannot be confirmed from prior submissions.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 17 tier-1 engines clean
- common_old prevalence (419 sources)
- no malicious sandbox verdict
- no malicious dropped children
Retain the file; the single low-trust detection is consistent with a false positive on a long-standing legitimate installer.

Detection sources at a glance
The available sources did not agree on a named threat category.
MalwareBazaar, YARAify, and CIRCL hashlookup completed and returned no entries for this hash.
Signatures and behavior heuristics
Behavioral heuristics matched patterns associated with malware. Corroborating evidence determines how much weight they carry.
The sample contacted an external IP address directly and no application domain was recorded. Direct-IP traffic also occurs in legitimate installers and infrastructure, so this is supporting context only and requires corroboration from host reputation and other runtime evidence.

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.
