Verdict Suspicious
Is T4est safe? Treat it as suspicious.
This Linux executable has one machine-learning detection from Microsoft out of 75 engines and no other hostile evidence, but it is rare and nothing has observed its behaviour.
Read the whole reasonShow less
Why Suspicious? One antivirus engine (Microsoft) flags it; nothing else confirms it.
Limited evidence
If it came from a link, an attachment or a stranger, delete it.
What to do now5 steps
Some signs point to a problem, but nothing confirms it is harmful. Treat it with caution.
What to do
Don't open 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.
It is less than a day old. If you're unsure, scan it again in a few days; antivirus engines often catch up on new files.
If you already opened it
Stop using it, run a full scan with your antivirus and watch for unexpected behavior or security alerts.

Why we think so
3 points against it and 2 in its favour, checked against the scan evidence.
The reasoning behind this verdict
Only Microsoft flagged this 64-bit Linux executable, with a generic machine-learning label. 17 other major antivirus engines did not flag it. It was first seen on Oct 25, 2026 from a single source. We have no sandbox run, no inspection of its contents and no reference-database entry, so there is not enough evidence for a confident call.
One of the 63 antivirus engines that checked it flagged the file: Microsoft, with a generic machine-learning trojan label that names no malware family. No other major or mid-tier engine flagged it, which points toward a possible false positive. However, the file is rare and new, with a single submitter, and is not a known reference file. No sandbox run or static inspection of its contents is available, so its behaviour is unobserved. Without a benign anchor or any corroborating hostile evidence, the evidence is too thin to call it either way.
What We Detected
This is a 64-bit Linux executable of about 8.6 MB, first seen on Oct 25, 2026. One of the 63 antivirus engines that checked it flagged it: Microsoft reported a generic machine-learning trojan label. None of the other engines, including 17 other major antivirus engines, flagged it. The file has no entries in malware-sharing databases, community rule sets or known-software references.
Threat Behavior
No observation from the test run is available, and nobody has inspected the file's contents. Its network activity and actions are therefore unknown. The lone detection names no malware family and is the kind of automated label that sometimes misfires on unusual binaries.
What To Do Now
If you did not build this file yourself or get it from a trusted source, do not run it. Rescan it later as more engines and analyses report, or run it only in an isolated test system.
Where this verdict could be wrong1 caveat
- The single Microsoft detection is a machine-learning label in a generic bucket, and no other engine agrees with it. That shape is often a false positive.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 74 of the 63 antivirus engines that checked it did not flag it, including 17 other major antivirus engines
- No listing in malware-sharing databases or community malware rules
- Microsoft flagged it with a generic machine-learning trojan label
- Rare file with a single submitter, first seen on Oct 25, 2026
- No sandbox run or inspection of its contents is available
