Is XenoUI.dll safe?
Five tier-1 engines flagged this DLL, mostly as unwanted downware, while runtime evidence indicates possible process injection and defense impairment.
Eleven of 75 engines flagged the sample, including five high-trust engines, with several identifying downware or potentially unwanted software. One sandbox run also mapped activity to process injection and impairment of defenses, while the unverified trust status of the signer offers little reassurance.

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.
Eleven of 75 engines flagged the sample, including five high-trust engines, with several identifying downware or potentially unwanted software. One sandbox run also mapped activity to process injection and impairment of defenses, while the unverified trust status of the signer offers little reassurance.
The detection count is meaningful: 11 of 75 engines flagged the file, including five tier-1 engines. DrWeb, Microsoft, Ikarus, and Sophos mainly describe adware or potentially unwanted software, but the family labels do not form strong tier-1 consensus. A completed sandbox run mapped activity to T1055 process injection and T1562.001 impairment of defenses, which materially raises concern despite no explicit malicious sandbox verdict. The signer has no established history or curated publisher match, and its verification status is unavailable. No researcher-rule, known-malware-database, or malicious-child corroboration was found, leaving some uncertainty about whether this is aggressive unwanted software or more harmful code.
What We Detected
Eleven of 75 antivirus engines flagged XenoUI.dll, including five tier-1 engines. DrWeb called it Adware.Downware.20251, Microsoft reported PUA:Win32/Packunwan, Ikarus reported PUA.GameHack.Xeno, and Sophos reported a generic PUA. These labels point mainly toward downware or unwanted software, although Symantec also produced a high-confidence generic machine-learning detection.
Threat Behavior
One completed sandbox observation mapped activity to T1055, associated with process injection, and T1562.001, associated with impairing defenses. Those mappings are concerning but do not prove the exact implementation or intent, and the sandbox did not issue an explicit malicious verdict. No network contacts were recorded in that run; however, no complete contacted-host reputation result is available. One dropped child was inspected without a malicious finding, but it remained unclassified.
What To Do Now
Do not load this DLL or allow it to run on a production system unless its origin and purpose can be independently verified. Keep endpoint protection enabled, quarantine the file, and obtain a fresh copy only from the software publisher's official release channel if the component is expected.
Where this verdict could be wrong5 caveats
- 12 of 17 tier-1 engines did not flag the file, including Avast, BitDefender, ESET-NOD32, and Fortinet.
- behaviour.hasMaliciousSandboxVerdict=false, although the run still mapped activity to T1055 and T1562.001.
- externalIntel.yaraify.ruleCount=0 and externalIntel.malwareBazaar.hit=false; absent hits can reflect intelligence-coverage gaps.
- droppedChildren.hasMaliciousChild=false, but the sole child remained unclassified.
- contactedHosts is null, so no complete host-reputation cross-check is available.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 12 of 17 tier-1 engines did not flag the sample
- No explicit malicious sandbox verdict
- No malicious dropped child identified
- No YARAify or MalwareBazaar corroboration
- No packing or high-entropy code detected
- 11/75 antivirus detections
- Five tier-1 engine detections
- Runtime mapping to T1055 process injection
- Runtime mapping to T1562.001 impairment of defenses
- No established history for signer 'Rizve A'
- Signature verification status is unavailable
Quarantine the DLL and avoid loading it until the publisher and download source are verified. Keep security protection enabled and replace it with a copy obtained through an official release channel.

What this file does
Observed actions and their security significance
High concern: Injected code into another process, a technique that can conceal execution.
High concern: Attempted to impair or bypass security controls.
High concern: Manipulated how the operating system loads code, which can redirect execution.
Moderate concern: Contained obfuscated or packed code that makes inspection harder.
Moderate concern: Runs hidden system commands (script or shell).
Moderate concern: Removed execution artefacts or logs, which can conceal activity.
Moderate concern: Communicated over a common application protocol; malware can use this for command-and-control.
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.

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.

What to do now
We couldn't fully clear this file. Treat it with caution.
- Recovery step 01
Don't use it unless you're certain it came from a source you trust.
- Recovery step 02
Check where you got it — an unexpected attachment or a random download link is a red flag.
- Recovery step 03
Do not delete or replace the component manually. Quarantine it with your antivirus or repair the parent software from its official source. Reinstall the parent software from the developer's official site instead of replacing this component by itself.
- Recovery step 04
If you're still unsure, scan it again in a day or two — detections often catch up on newer files.
