Why Suspicious? 9 antivirus engines flag it; nothing else confirms it.
Limited evidence · One sign points to a problem; nothing else confirms it.
If it came from a link, an attachment or a stranger, delete it.
What to do now4 steps
Some signs point to a problem, but nothing confirms it is harmful. Treat it with caution.
What to do
Don't run it unless you're sure where it came from.
Check where you got it: an unexpected attachment, a link someone sent you or a re-upload is a red flag.
If you can't confirm where it came from, delete it. If you need the program, download it again from the publisher's own website.
If you already ran it
Stop using it, run a full scan with your antivirus and watch for unexpected behavior or security alerts.

Why we think so
5 points against it and 4 in its favour, checked against the scan evidence.
The reasoning behind this verdict
The file has substantial warning signs: 9 of the 70 antivirus engines that checked it flagged it, including two major detections, and several labels identify Yogi. However, the detections collapse to three independent votes, while one sandbox run found no offensive behavior and the observed host had no adverse reputation entry, leaving meaningful uncertainty.
Nine of the 70 antivirus engines that checked it flagged the executable, with two major detections and three independent engine votes after vendor relationships were collapsed. BitDefender and Emsisoft use the Yogi label, while TrendMicro-HouseCall reports a generic trojan label, so the family attribution has support but not strong major consensus. The executable is unsigned and has no publisher history to counterbalance those detections. Conversely, the completed sandbox run returned clean, recorded no high-risk techniques, and the fully inspected contacted domain had no malicious or suspicious cache entry. No malware-specific external-intelligence hit, malicious child, packing indicator, or high-entropy code corroborates the engine findings, making isolation and source verification more appropriate than execution.
What We Detected
Nine of the 70 antivirus engines that checked it flagged CyberleekViewer.exe. Two major antivirus engines contributed detections, and the results reduce to three independent engine votes after related products are accounted for. BitDefender and Emsisoft identify Gen:Variant.Yogi.88021, while TrendMicro-HouseCall reports TROJ_GEN.R002H09J126. The file is unsigned, so there is no verified publisher identity to help establish provenance.
Threat Behavior
One completed sandbox run did not issue a malicious verdict and recorded no high-risk techniques, persistence changes, injected processes, written files, or files it created. Its only observed domain was fully covered by the host-reputation check and had no malicious or suspicious cache entry. No malware-specific YARAify rules, MalwareBazaar record, high-entropy code, or recognized packer provided additional corroboration. A prior malicious file shared the import-table fingerprint, but it had a different filename and no matching signer, so that similarity is supporting context rather than proof.
What To Do Now
Do not run the file on a normal system unless its origin and expected publisher can be independently verified. Keep security software enabled, let your antivirus remove the executable, and obtain a fresh copy from the software publisher's official release channel if the program is needed.
Where this verdict could be wrong4 caveats
- The completed sandbox run did not issue a malicious verdict and recorded no high-risk techniques.
- The one observed contacted domain was fully covered by the host-reputation check and had no malicious or suspicious cache entry.
- Most engines did not flag the file, and the Yogi family agreement does not meet the strong major consensus threshold.
- No malware-specific YARAify rule, MalwareBazaar record, malicious file it created, packing indicator, or high-entropy code was found.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- One completed sandbox run did not issue a malicious verdict.
- No high-risk techniques, injected processes, persistence changes, or dropped files were observed.
- The one observed domain was fully inspected and had no malicious or suspicious reputation entry.
- No malware-specific external-intelligence match, recognized packer, or high-entropy code was found.
- Nine of the 70 antivirus engines that checked it reported malicious detections.
- Two major antivirus engines flagged the executable.
- Several detections use the Yogi trojan label.
- The Windows executable is unsigned and has no established publisher history.
- A previously analyzed malicious file shared the same import-table fingerprint, although the publisher relationship could not be established.

What the test run showed
What the file did on a test computer
Confirmed in the test run
Moderate concern: Contains packed or scrambled code that is harder to inspect (common in installers too).
Moderate concern: Ran commands or a script on the test computer.
Moderate concern: Checked whether it was running on a test computer.
Note: Listed the programs running on the test computer.
Note: Read basic details of the test computer, such as its Windows version.
Note: Looked through folders on the test computer (most installers do this).
Note: Loaded extra code modules while running.
Sandbox labels we could not confirm (common in safe files too)
Not confirmed: A sandbox rule tagged this run as contacting a server, but no contacted host was recorded.
This file was run on a test computer (a sandbox), not on yours. Labels we could not confirm are listed so you can see them, but they are not treated as evidence against the file.
