Is KeyScrambler3.19.0.3_Setup.exe safe?
No antivirus engine detected this signed installer, although its very recent appearance and lack of completed runtime observation warrant routine source verification.
All 75 antivirus engines were free of detections, including 17 tier-1 engines, and the executable carries a verified QFX SOFTWARE CORPORATION signature. Confidence is tempered by its first-day prevalence, limited signer history, and absence of completed sandbox execution, so obtain it from the publisher's official channel.

Before installing
Install it only when it came from the developer's official site or an official app store.
If you already installed it
Keep normal device protection enabled and stop if the file behaves unexpectedly.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
All 75 antivirus engines were free of detections, including 17 tier-1 engines, and the executable carries a verified QFX SOFTWARE CORPORATION signature. Confidence is tempered by its first-day prevalence, limited signer history, and absence of completed sandbox execution, so obtain it from the publisher's official channel.
The strongest evidence is the complete absence of detections across 75 antivirus engines, with all 17 reporting tier-1 products returning no detection. The executable is also validly signed by QFX SOFTWARE CORPORATION, and no brand mismatch was detected. Static PE analysis did not identify packed or high-entropy code sections, while external intelligence produced no known-malware or YARA matches. No completed sandbox run is available, so the listed T1134 indicator cannot be treated as observed runtime conduct, and no complete contacted-host reputation result is available. The file is newly observed with only one submission, and the signer's history contains just one prior sample, which keeps confidence below the highest level. The imphash comparisons involve unrelated signers and therefore provide little additional assurance.
What We Detected
None of 75 antivirus engines flagged the executable, including all 17 reporting tier-1 engines. The file has a verified signature from QFX SOFTWARE CORPORATION, no detected brand mismatch, and no known-malware, YARA, or research-database hit.
Threat Behavior
No completed sandbox execution is available because behaviour.sandboxCount=0. T1134 appears in static behavioral indicators, but without runtime corroboration it is not enough to establish abuse. Static PE analysis reports neither likely packing nor high-entropy code sections. No complete contacted-host reputation result is available.
What To Do Now
Confirm that the installer came from the publisher's official download channel and that Windows still shows the QFX SOFTWARE CORPORATION signature as valid. Keep endpoint protection enabled and rescan if the signature, source, or file hash differs.
Where this verdict could be wrong4 caveats
- behaviour.offensiveTechniques includes T1134, but behaviour.sandboxCount=0 means it was not corroborated by completed runtime observation.
- signing.signerStats records only 1 prior sample, so the signer's 100% safeRate is not statistically established.
- contactedHosts=null means no complete host-reputation cross-check is available.
- Three of five similarHashes entries were previously suspicious, but all are imphash-only matches from different or absent signers.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/75 antivirus detections
- All 17 reporting tier-1 engines returned no detection
- Verified QFX SOFTWARE CORPORATION signature
- No brand mismatch detected
- No packing, known-malware, or YARA match
- Observed for the first time today with only one submission
- Signer history contains only one prior sample
- No completed sandbox runtime observation
- Static technique indicator T1134
- No complete contacted-host reputation cross-check
Use the installer only if it came from the publisher's official channel and its QFX SOFTWARE CORPORATION signature remains valid. Keep endpoint protection enabled and rescan after additional reputation develops.

How widely this file has been seen
Barely seen in the wild and first surfaced recently. That limits reputation evidence, but rarity alone is not proof of malware.
