Is version.dll safe?
Only 2 of 75 engines raised generic low-trust alerts, while established prevalence, tier-one silence, and observed behavior provide no corroborating malware evidence.
APEX and Trapmine produced the only alerts among 75 engines, and neither is a tier-one detection or names a malware family. One completed sandbox run found no malicious verdict, offensive technique, persistence, or network contact, while the file has circulated broadly for more than two years.

Before using
Use it only as part of software obtained from the developer's official site or another source you independently trust.
If you already used 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.
APEX and Trapmine produced the only alerts among 75 engines, and neither is a tier-one detection or names a malware family. One completed sandbox run found no malicious verdict, offensive technique, persistence, or network contact, while the file has circulated broadly for more than two years.
Only 2 of 75 engines flagged this DLL, and both alerts came from low-trust detectors using generic or machine-learning labels. Sixteen reporting tier-one engines, including Avast, BitDefender, ESET, Kaspersky, and Fortinet, did not detect it, and there is no family consensus. One sandbox run observed DLL execution and other ambient Windows activity but produced no malicious verdict, offensive technique, persistence indicator, or network contact. The file is neither packed nor high-entropy and has appeared in 164 submissions from 127 sources over 837 days. The unsigned status and unknown child-artifact verdicts reduce certainty, but the available evidence strongly supports a false-positive explanation.
What We Detected
Only 2 of 75 antivirus engines raised alerts: APEX reported a generic malicious result, and Trapmine returned a generic machine-learning score. Both are low-trust detections; engines.tier1Malicious=0, and no engine family consensus exists. The file is unsigned, so there is no verified publisher identity to strengthen attribution.
Threat Behavior
One completed sandbox run recorded DLL loading, user-input checks, system discovery, and environment-detection activity. These observations produced no malicious sandbox verdict, no offensive-only MITRE techniques, no persistence indicators, and no contacted domains, IP addresses, or URLs. No complete host-reputation cross-check is available because contactedHosts was not saved. Eight written artifacts were inspected without a known malicious child, although their individual verdicts remain unknown.
What To Do Now
The low-trust-only detection pattern, broad historical prevalence, lack of packing, and absence of corroborating external intelligence point toward generic false alarms. Keep endpoint protection enabled and obtain the DLL from its original trusted software package; if it appeared unexpectedly or is loaded by an unfamiliar application, quarantine it and verify the parent program before use.
Where this verdict could be wrong4 caveats
- signing.applicable=true but signing.signed=false, so no publisher identity or signer history supports the file.
- The sandbox recorded T1056, T1497, and T1574.002, including input checks, environment detection, and DLL-loading activity; these are ambient here but merit context-aware caution.
- contactedHosts=null, so no complete host-reputation cross-check is available.
- All 8 inspected dropped children have unknown verdicts despite droppedChildren.hasMaliciousChild=false.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- engines.tier1Malicious=0 with 16 reporting tier-one engines clean
- behaviour.hasMaliciousSandboxVerdict=false and behaviour.offensiveCount=0
- No persistence indicators or observed network contacts
- prevalence shows 127 sources and 164 submissions over 837 days
- peAnalysis.highEntropyCode=false and peAnalysis.likelyPacked=false
- Unsigned Win32 DLL with no verified publisher identity
- 2/75 generic low-trust antivirus detections
- Sandbox recorded environment detection and DLL-loading techniques
- Eight child artifacts have unknown individual verdicts
- No complete contacted-host reputation result is available
Keep endpoint protection enabled and use the DLL only if it came with a trusted, expected application. If its origin is unknown or it appeared unexpectedly, quarantine it and reinstall the associated program from its official source.
