Is Unconfirmed 99906.crdownload safe?
Only 1 of 75 engines raised a generic detection, while all 17 tier-1 engines found nothing and no threat family was corroborated.
The lone K7GW generic Trojan label is not supported by any tier-1 engine, named-family consensus, or external intelligence match. Because the JAR is newly observed and has no sandbox results, retain normal caution and verify its download source before opening it.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
The lone K7GW generic Trojan label is not supported by any tier-1 engine, named-family consensus, or external intelligence match. Because the JAR is newly observed and has no sandbox results, retain normal caution and verify its download source before opening it.
Only K7GW flagged the sample, producing a generic Trojan label among 75 engines. All 17 tier-1 engines reported no detection, including Microsoft, Kaspersky, BitDefender, and ESET-NOD32. No named malware family, YARA rule, known-malicious intelligence record, or malicious child corroborates the isolated result. The five prior safe records are merely file-type matches, so they offer limited support rather than strong similarity evidence. The sample is rare and newly observed, and no completed runtime or full host-reputation assessment is available, which prevents stronger assurance.
What We Detected
K7GW was the only engine to flag the file, assigning the generic label “Trojan ( 0000c3511 )”. The remaining results include no tier-1 detections, and all 17 tier-1 engines that contributed—including Microsoft, Kaspersky, BitDefender, and ESET-NOD32—reported no detection. There is no agreed malware family and no matching YARA rule or known-malicious external-intelligence record.
Threat Behavior
No completed sandbox observation is available, so the file's runtime actions have not been established. A complete reputation check for any contacted hosts is also unavailable. The sample is newly observed with only one recorded submission, which limits reputation-based confidence.
What To Do Now
Confirm that the JAR came from the intended official source and compare its hash or release signature if the publisher provides one. Keep endpoint protection enabled, and avoid running the file if the incomplete-download filename or source is unexpected.
Where this verdict could be wrong3 caveats
- K7GW, a tier2 engine, reported the generic label "Trojan ( 0000c3511 )"; this remains an uncorroborated detection rather than a named-family consensus.
- The file is newly observed with one submission, so its reputation is not yet established.
- No sandbox run or complete contacted-host reputation result is available, limiting behavioral assurance.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- All 17 tier-1 engines reported no detection.
- Only 1 of 75 engines flagged the sample.
- No tier-1 family consensus was found.
- YARAify returned zero matching rules.
- MalwareBazaar and CIRCL returned no matching malicious record.
- K7GW reported a generic Trojan detection.
- The JAR is newly observed with one recorded submission.
- No completed runtime observation is available.
- No complete contacted-host reputation result is available.
- The .crdownload filename indicates an incomplete or interrupted browser download.
Verify the download source and obtain a complete copy with a normal .jar filename before use. Keep endpoint protection enabled and rescan the completed file if it changes.
