Is setup.exe safe?
The unsigned installer showed process-injection and defense-evasion indicators, contacted a suspicious host, and drew one tier-1 detection without broader family consensus.
Execution produced four offensive indicators, including process injection and impairment of defenses, while contacting a host already regarded as suspicious. Only 2 of 76 engines flagged the file and no strong family consensus or explicit sandbox malware judgment exists, so the evidence remains mixed rather than conclusive.

Before installing
Do not install it until the source and publisher can be verified independently.
If you already installed it
Stop using it, scan the device, and watch for unexpected behavior or security alerts. Download a fresh installer from the developer's official site or an official app store.
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.
Execution produced four offensive indicators, including process injection and impairment of defenses, while contacting a host already regarded as suspicious. Only 2 of 76 engines flagged the file and no strong family consensus or explicit sandbox malware judgment exists, so the evidence remains mixed rather than conclusive.
GData and Webroot flagged the sample, but only GData is tier-1 and the single PSEB label does not establish family consensus. A completed sandbox mapped activity to T1055, T1055.011, T1134, and T1562.001, which is materially riskier than ordinary installer activity. The sample also contacted fitgirl-repacks.site, a host marked suspicious in the available cache results, though complete reputation coverage of every observed host is not established. The executable is unsigned and therefore lacks a publisher identity that could explain or offset these findings. Against that, no explicit malware sandbox judgment or malicious dropped child was recorded, and most engines did not detect it. The imphash history is mostly unfavorable, but those matches lack signer co-matching and may reflect a shared installer framework rather than a common payload.
What We Detected
Two of 76 antivirus engines flagged the file. GData reported Generic.Trojan.PSEB.Z563F3, while Webroot supplied a generic malware label; only the GData result is tier-1, so there is no strong family consensus.
Threat Behavior
One completed sandbox run recorded four offensive techniques: T1055 and T1055.011 for process injection, T1134 for access-token manipulation, and T1562.001 for impairing defenses. It also contacted fitgirl-repacks.site, which is marked suspicious in the available host cache. The host check does not clearly cover every distinct observed domain and IP, so no complete network-reputation conclusion is available. Ten dropped files were inspected without a malicious-child finding, but their individual verdicts remain unknown.
What To Do Now
Do not run this installer on a production or personal system unless its origin and integrity can be independently verified. Keep endpoint protection enabled, obtain software from an official publisher channel, and quarantine or remove the file if its source cannot be trusted.
Where this verdict could be wrong4 caveats
- Only 2/76 engines detected the sample, and 13 tier-1 engines reported it undetected; the sole tier-1 PSEB family vote is not consensus.
- behaviour.hasMaliciousSandboxVerdict=false, so the completed sandbox did not issue an explicit malware judgment despite the offensive techniques.
- droppedChildren.hasMaliciousChild=false, although all 10 inspected children have unknown individual verdicts rather than confirmed clean results.
- externalIntel.yaraify.ruleCount=0, externalIntel.circl.hit=false, and externalIntel.malwareBazaar.hit=false; these absences may reflect coverage limitations.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Only 2/76 engines flagged the sample, with no strong tier-1 family consensus.
- behaviour.hasMaliciousSandboxVerdict=false.
- droppedChildren.hasMaliciousChild=false across 10 inspected children.
- externalIntel.yaraify.ruleCount=0 and externalIntel.malwareBazaar.hit=false.
- peAnalysis.highEntropyCode=false and peAnalysis.likelyPacked=false.
- Runtime evidence includes process injection techniques T1055 and T1055.011.
- Runtime evidence includes access-token manipulation T1134.
- Runtime evidence includes defense impairment T1562.001.
- The sample contacted fitgirl-repacks.site, listed in contactedHosts.suspiciousHosts.
- The Win32 installer is unsigned and has no signer history.
- GData supplied a tier-1 generic-trojan detection.
Quarantine the file and verify its hash and download source against an official publisher release before use. Keep antivirus and endpoint protection enabled; use an isolated analysis environment if further examination is necessary.

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.
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.
Moderate concern: Scans through your files and folders.
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.

Detection sources at a glance
The available sources did not agree on a named threat category.
MalwareBazaar, YARAify, and CIRCL hashlookup completed and returned no entries for this hash.
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 install 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
If its origin cannot be confirmed, delete this file and use a fresh copy from a trusted source. Download a fresh installer from the developer's official site or an official app store.
- Recovery step 04
If you're still unsure, scan it again in a day or two — detections often catch up on newer files.
