Is stvoyHM.v1.10 safe?
Unsigned 15-year-old executable with zero engine detections and minimal external intel.
No antivirus engine flagged the file and no tier-1 consensus exists. A single community YARA rule matched, but the sample remains rare and unsigned with no sandbox or host-reputation data available.

Before opening
Treat the file as unverified and avoid opening it until more evidence is available.
If you already opened it
Run a full device scan. If its origin cannot be confirmed, delete this file and use a fresh copy from a trusted source.
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.
No antivirus engine flagged the file and no tier-1 consensus exists. A single community YARA rule matched, but the sample remains rare and unsigned with no sandbox or host-reputation data available.
The complete absence of malicious detections across 77 engines, including 18 tier-1 engines reporting clean, is a strong benign indicator. However, the file is unsigned, has only been seen once since 2011, and lacks any sandbox or contacted-host analysis. The single YARAify rule match is inconclusive without additional context. Low coverage and missing runtime evidence prevent a confident classification.
What We Detected
77 engines scanned the sample; none returned a malicious or suspicious result. One community YARA rule (Check_OutputDebugStringA_iat) triggered on YARAify, but no named malware family was identified.
Threat Behavior
No sandbox execution data, no contacted domains or IPs, and no dropped children were recorded. The file remains unsigned with no signer history.
What To Do Now
Because coverage and runtime evidence are limited, treat the file as untrusted until additional analysis (sandbox execution, code review, or broader engine coverage) can be obtained. Keep endpoint protection enabled.
Where this verdict could be wrong2 caveats
- Single YARAify rule match could indicate either benign anti-debugging code or an undetected malicious sample; rule coverage gaps prevent definitive interpretation.
- File age of 5580 days with only one submission suggests either a very niche legitimate tool or an old undetected threat that never spread.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.

Signatures and behavior heuristics
A community signature or high-severity behavioral heuristic matched. Signatures identify known patterns; heuristics are strong leads but are not proof on their own.

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
Rarely uploaded, but has been around for a while. Often niche legitimate software or old internal tooling; not a strong malware signal on its own.

What to do now
There isn't enough information to give this file a clear rating.
- Recovery step 01
Be cautious — an unknown rating is not the same as a clean bill of health.
- Recovery step 02
Open it only when its sender or download source is one you independently trust.
- Recovery step 03
When in doubt, don't open it — or scan it again later once it's more widely seen.
