Why we think so
1 point against it and 4 in its favour, checked against the scan evidence.
The reasoning behind this verdict
None of the 69 antivirus engines that checked it flagged this installer, including all major antivirus engines. Thousands of distinct sources have submitted it. In the sandbox runs it installed and launched qBittorrent and wrote only normal configuration files.
None of the 69 antivirus engines that checked it flagged the file, and every major antivirus engine returned clean. More than 3,600 distinct sources have submitted it, which fits a popular open-source torrent client. The sandbox runs show a standard installer that writes temporary setup files, creates qBittorrent settings and launches the application. No injection target or other high-risk technique was recorded. The YARA matches only identify the Nullsoft installer framework, and the automated community labels rest on generic installer traits. The missing code signature is the main gap, but it is not hostile evidence.
What We Detected
None of the 69 antivirus engines that checked it flagged this installer, and all major antivirus engines reported it clean. Community YARA matches identify only the Nullsoft (NSIS) installer framework and generic capabilities. The file is not listed in public malware databases. More than 3,600 distinct sources have submitted it.
Threat Behavior
In the sandbox runs, the setup program extracted standard installer components, installed qBittorrent and launched it. It then wrote ordinary configuration and log files. No injection into other processes, persistence or suspicious network activity was recorded. The file is unsigned, so there is no publisher signature to confirm its origin.
What To Do Now
If you obtained this installer from the official qBittorrent website or its official release channel, it is fine to install. Keep your antivirus enabled. If the file came from a third-party mirror, re-download it from the official source.
Where this verdict could be wrong2 caveats
- The installer is unsigned, so no publisher identity confirms it is the official qBittorrent build. A tampered repack cannot be fully excluded, although zero detections and broad prevalence make that unlikely.
- Automated community analyses labelled the file malicious based on generic installer tags such as anti-debug and packed. No antivirus engine corroborates those labels.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- None of the 69 antivirus engines that checked it flagged the file, including every major antivirus engine
- Widely seen, with more than 3,600 distinct sources and over 40,000 submissions
- Sandbox runs showed only normal installation of qBittorrent, with no high-risk techniques
- YARA matches only identify the common Nullsoft installer framework
- The installer carries no code signature, so its publisher cannot be verified from the file itself.

Signatures and behavior heuristics
Community YARA rules matched, but all of them are generic capability, anti-debug or compiler rules that ordinary software also matches. Worth noting, not on their own cause for alarm.

VirusTotal's sandbox summary maps this run to MITRE T1055 (Process Injection), but no injected process of the sample's own was recorded (the analysis VM's own WMI adapter, crash handlers and Chrome updater are not counted). VirusTotal maps T1055 on about half of all files no engine flags, so the mapping alone is not evidence of injection.
