Is PhotovoltaiqueClass.dll safe?
Unsigned DLL with zero detections across 74 engines and mixed but mostly clean imphash history.
No engine flagged the file. The unsigned status and single direct-IP contact are neutral signals given the absence of malicious sandbox verdicts or dropped children.

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.
No engine flagged the file. The unsigned status and single direct-IP contact are neutral signals given the absence of malicious sandbox verdicts or dropped children.
Zero detections from 74 engines including 17 tier-1 engines rules out any named malware family. The file is unsigned, which is common for internal or research DLLs. Two of three similar imphash samples were previously marked safe. The single sandbox run showed only ambient techniques and no malicious verdict. The direct-IP heuristic is explicitly low-severity and cannot be confirmed malicious without host reputation data.
What We Detected
74 engines scanned the 12.5 MB Win32 DLL; none returned a malicious or suspicious result. The file is unsigned and carries no code-signing certificate. Sandbox execution recorded nine ambient MITRE techniques and one external IP contact (162.159.36.2) but produced no malicious verdict and no dropped children.
Threat Behavior
No offensive techniques, persistence indicators, or registry modifications were observed. The direct-IP contact triggered a low-severity heuristic, yet the rule itself notes that such traffic occurs in legitimate installers. Host reputation for the IP is unavailable because contactedHosts was not populated.
What To Do Now
Keep existing endpoint protection enabled. If the DLL is required for a specific application, restrict its execution to a controlled environment and monitor for unexpected outbound connections until its legitimacy is confirmed by the software vendor.
Where this verdict could be wrong2 caveats
- similarHashes[0] returned malicious (Zusy) on imphash match without signer correlation — framework collision possible.
- contactedHosts=null means host reputation cross-check incomplete; direct-IP contact (162.159.36.2) cannot be fully assessed.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Zero detections across 74 engines
- No malicious sandbox verdict
- Two of three similar imphash samples previously marked safe
- File is unsigned
- Direct-IP contact observed without domain name
The file can be considered safe for normal use; continue monitoring only if it is executed from untrusted locations.

Signatures and behavior heuristics
Low-severity pattern matches — worth noting but not on their own cause for alarm.
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.
