Why we think so
0 points against it and 4 in its favour, checked against the scan evidence.
The reasoning behind this verdict
This file shows no signs of malware. All 48 reporting engines, including 17 major antivirus engines (Kaspersky, Microsoft, BitDefender, ESET-NOD32, Fortinet, McAfee), report it clean. The filename pattern suggests a device firmware binary, and no sandbox behaviour, files it created, or malicious host contact was detected. The file is old and rarely seen, consistent with an obsolete or archived firmware blob.
The evidence strongly indicates a benign file. Zero malicious detections across a broad antivirus network, with particular weight on 17 major antivirus engines all reporting clean, rules out known malware families. The unsigned status and rare prevalence (3 submissions over 15+ years) are consistent with an old firmware or binary archive rather than active malware. No sandbox execution data, no malicious behaviour, and no external intelligence hits (CIRCL, MalwareBazaar, YARAify) provide no counter-evidence. The filename pattern 'befw11s4v3.2_v1.45.10_code.bin' aligns with Belkin router firmware versioning, further supporting a legitimate device binary interpretation.
What We Detected
The antivirus engines scanned this file across 48 engines, including 17 major antivirus engines (Kaspersky, Microsoft, BitDefender, ESET-NOD32, Fortinet, McAfee, Emsisoft, F-Secure, GData, Ikarus, DrWeb, Avast, AVG, and others). Zero engines reported malicious or suspicious activity. All reporting engines classified the file as clean or undetected.
File Characteristics
The file is unsigned and carries no signer history. Its filename pattern ('befw11s4v3.2_v1.45.10_code.bin') is consistent with Belkin firmware versioning, suggesting a device binary rather than executable malware. The file is 757 KB in size and was first submitted in December 2009 — over 15 years ago — with only 3 total submissions from 3 unique sources. No recent activity or user feedback exists.
Threat Behavior
No sandbox execution data is available. No complete contacted-host reputation result was available, and no external intelligence hits (CIRCL, MalwareBazaar, YARAify) were recorded. The absence of any runtime malicious indicators, combined with unanimous engine silence, rules out active malware.
What To Do Now
This file appears to be a legitimate firmware or archived binary blob. If you encountered it as part of a device update or archive, it is safe to use. If you have concerns about its origin, verify it against the official Belkin firmware repository or your device manufacturer's support site.
Where this verdict could be wrong3 caveats
- File is unsigned and rare, which could mask older malware that predates modern detection signatures — however, 17 major antivirus engines with access to historical malware corpora would likely flag a known family if present.
- Limited evidence (48/50 reporting; 2 timeouts) could hide a detection, but the major antivirus engines that did report are unanimous in silence, making a missed malicious consensus unlikely.
- The .bin extension and firmware-like naming could indicate a device binary that legitimate security tools do not inspect deeply, but the absence of any malicious behaviour data or host contact rules out active malware.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/48 engines malicious; 17 major antivirus engines all clean
- No sandbox malicious verdict
- Filename consistent with legitimate firmware versioning
- No external intelligence hits (CIRCL, MalwareBazaar, YARAify)
