Is trayicon.dll safe?
Only 1 of 74 engines flagged this unsigned, newly observed DLL, but sandbox evidence mapped its execution to possible T1055 process injection.
The lone generic detection is weak and no tier-1 engine identified malware. However, the file is unsigned, newly observed, and one sandbox mapped its activity to possible process injection, so it should not be trusted without source verification.

Before using
Do not use it until the source and publisher can be verified independently.
If you already used it
Stop using it, scan the device, and watch for unexpected behavior or security alerts. Reinstall the parent software from the developer's official site instead of replacing this component by itself.
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.
The lone generic detection is weak and no tier-1 engine identified malware. However, the file is unsigned, newly observed, and one sandbox mapped its activity to possible process injection, so it should not be trusted without source verification.
Only 1 of 74 engines detected the DLL, and that result was a generic tier-2 label rather than a named family. All 17 reporting tier-1 engines were silent, which substantially weakens the detection. One completed sandbox run nevertheless mapped activity to T1055 Process Injection, an offensive technique that warrants caution even though the sandbox issued no malicious verdict. The DLL is unsigned and has only one submission on its first observed day, leaving little reputation or publisher history to support it. No external intelligence or similar-file history corroborates malware, and no complete contacted-host reputation result is available.
What We Detected
Only 1 of 74 antivirus engines flagged the DLL. The detecting engine, tehtris, used the generic label “Generic.Malware”; none of the 17 reporting tier-1 engines identified a threat family.
Threat Behavior
One completed sandbox observation mapped execution through rundll32 to MITRE T1055 Process Injection. This is a meaningful risk indicator, but the saved evidence does not establish the exact injection method or intent, and the sandbox did not issue a malicious verdict. No persistence indicators, dropped-file hashes, or network contacts were recorded. A complete contacted-host reputation cross-check was not available.
What To Do Now
Do not load the DLL on a production system until its origin and expected publisher are confirmed. Keep endpoint protection enabled, obtain a fresh copy from the official software source, and consider isolated re-analysis if the file is operationally necessary.
Where this verdict could be wrong3 caveats
- All 17 reporting tier-1 engines, including BitDefender, ESET-NOD32, Kaspersky, and Fortinet, returned no detection.
- behaviour.hasMaliciousSandboxVerdict=false, with no persistence indicators or dropped-file hashes recorded.
- The only detection is tehtris 'Generic.Malware', not a named family, and no external intelligence source corroborated it.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Only 1 of 74 engines reported a detection.
- engines.tier1Malicious=0, with 17 reporting tier-1 engines returning no detection.
- The only detection was a generic label rather than a named malware family.
- behaviour.hasMaliciousSandboxVerdict=false and no persistence indicators were recorded.
- MalwareBazaar, CIRCL, and YARAify provided no corroborating hits.
- Sandbox evidence mapped execution to MITRE T1055 Process Injection.
- The DLL is unsigned despite code signing being applicable.
- The file was newly observed with only one source and one submission.
- No established signer history or similar-file verdict history is available.
- A complete contacted-host reputation cross-check was not available.
Quarantine the DLL pending verification of its source and expected publisher, and avoid executing it through rundll32. Keep endpoint protection enabled and replace it with a copy obtained directly from the official vendor.

What this file does
Observed actions and their security significance
High concern: Injected code into another process, a technique that can conceal execution.
Moderate concern: Communicated over a common application protocol; malware can use this for command-and-control.
Note: Reads your Windows user-account details.
Note: Collects details about your system.
These are observed capabilities from an isolated analysis. A technique does not prove malicious intent on its own, and the file never ran on your device.

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
A community signature or high-severity behavioral heuristic matched. Signatures identify known patterns; heuristics are strong leads but are not proof on their own.
The saved runtime evidence maps this activity to MITRE T1055 (Process Injection). The mapping supports possible process injection, but it does not prove the exact injection method or the operator's intent.

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
Barely seen in the wild and first surfaced recently. 1 antivirus detection make that low prevalence materially relevant, but rarity alone is not proof of malware.
