Is Setup.exe safe?
Only Webroot flagged this widely seen installer as repack riskware, while tier-1 engines, the completed sandbox, and inspected children supplied no corroborating malware finding.
Webroot alone flagged the file as repack riskware; none of the tier-1 engines detected it. Its long-standing prevalence, non-malicious sandbox result, and absence of identified malicious children make a false positive likely, although the unsigned status and T1134 observation warrant obtaining it from a trusted source.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
Webroot alone flagged the file as repack riskware; none of the tier-1 engines detected it. Its long-standing prevalence, non-malicious sandbox result, and absence of identified malicious children make a false positive likely, although the unsigned status and T1134 observation warrant obtaining it from a trusted source.
Only 1 of 75 engines raised a detection, and that result came from low-trust Webroot rather than a tier-1 engine. The sample has circulated since May 2023 across 737 sources and 874 submissions, which weighs against an emerging malware campaign. One sandbox run did not produce a malicious conclusion, and none of ten inspected dropped files was identified as malicious. T1134 and the lack of a digital signature remain meaningful cautions, but they do not independently establish harmful activity. Prior imphash matches were concerning, yet they lacked signer co-matches and may reflect a shared installer framework rather than shared payload code. The host-reputation review was incomplete because it did not cover every observed network contact.
What We Detected
Webroot was the sole detector among 75 engines, labeling the executable W32.Riskware.Repack. No tier-1 engine reported malware, and curated external checks returned no matching malware family or research rule.
Threat Behavior
A completed sandbox run recorded mostly installer-common activity plus T1134, a technique associated with access-token manipulation. The run did not return a malicious conclusion, no persistence indicators were recorded, and none of ten inspected dropped children was identified as malicious. The host-reputation review covered the three named domains but not every observed IP address, so it does not provide a complete network assessment.
What To Do Now
Use the installer only if it came from the software publisher or another trusted distribution channel. Keep endpoint protection enabled, verify the expected product and checksum when available, and avoid running the file if its origin is uncertain.
Where this verdict could be wrong5 caveats
- The executable is unsigned: signing.applicable=true and signing.signed=false, so publisher authenticity cannot be established.
- T1134 was observed in the completed sandbox run and can indicate access-token manipulation, although no malicious sandbox conclusion accompanied it.
- Three communityComments describe suspicious or likely-malicious assessments, but these annotations are uncorroborated by tier-1 engine detections or curated external intelligence.
- The contacted-host check inspected only 3 hosts despite numerous observed IP addresses, so its empty maliciousHosts array is incomplete coverage.
- All five imphash-related prior samples received suspicious or malicious verdicts, though the absent signer co-match makes framework collision a substantial limitation.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- No tier-1 engine detected malware among 75 engines.
- Only one low-trust engine reported a detection.
- The file has 737 sources and 874 submissions dating back to May 2023.
- The completed sandbox did not issue a malicious conclusion.
- Ten inspected dropped children produced no identified malicious child.
- Unsigned Win32 executable with no verifiable publisher identity.
- Webroot labels it W32.Riskware.Repack.
- Sandbox activity includes MITRE technique T1134.
- Complete reputation coverage was unavailable for all observed network contacts.
- Five imphash-related samples had suspicious or malicious prior outcomes, although all lacked signer co-match.
Obtain a fresh copy from the official publisher and compare its checksum before use. Keep antivirus and endpoint protection enabled, especially because this copy is unsigned.
