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.
Our analysis indicates this file is likely safe. While it is unsigned and performs ambient extraction typical of installers, it lacks any confirmed malicious behavior or high-trust engine detections.
The file exhibits no offensive techniques and was not flagged by any high-trust security engines. The single detection from a low-trust engine is insufficient to classify the file as malicious. The observed ambient behavior is consistent with standard installer activity. As the file is unsigned, it lacks the verification of a trusted publisher, but the overall evidence does not support a malicious verdict.
What We Detected
Our analysis of the file EFMI_Fix_E.exe shows that it is an unsigned 64-bit executable. Out of 74 engines in our network, only one low-trust engine flagged the file, while 17 high-trust engines reported it as clean. There is no consensus on any malicious threat family.
Threat Behavior
The sandbox analysis observed ambient behavior, including the extraction of various DLLs to a temporary directory. This is a common pattern for legitimate software installers. No offensive MITRE techniques were identified, and the file did not exhibit any malicious sandbox verdicts or dropped malicious children.
What To Do Now
The file appears to be a standard, albeit unsigned, utility. We recommend keeping your endpoint protection enabled as a best practice. If you did not intentionally download this file, it is safer to remove it.
Where this verdict could be wrong3 caveats
- The file is unsigned, which prevents verification of its origin and integrity, leaving it inherently more suspicious than signed commercial software.
- The high entropy (7.99) and extraction of multiple DLLs to a temporary folder are common patterns in both legitimate installers and malicious droppers, creating ambiguity.
- The direct IP contact (162.159.36.2) is an unverified network connection that could potentially be used for telemetry or updates, but lacks sufficient reputation data to confirm its safety.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 17/17 tier-1 engines reported clean
- No offensive MITRE techniques
- No malicious sandbox verdict
- Medium prevalence (169 submissions)
- Unsigned executable
- High entropy (7.99)
- Direct IP network contact
The file is likely safe to use, but as it is unsigned, ensure it was obtained from a trusted source. Keep your security software enabled.

Detection & Forensics
Consensus, attribution, signatures, code structure, prevalence, and identity.
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
Low-severity pattern matches — worth noting but not on their own cause for alarm.
The sample contacted an external IP address directly and no application domain was recorded. Direct-IP traffic also occurs in legitimate installers and infrastructure, so this is supporting context only and requires corroboration from host reputation and other runtime evidence.

What to do now
This file appears low risk based on the evidence available now.
Run it only when it came from the developer's official site or another source you independently trust.
A clean result reduces known risk, but it cannot guarantee that every new or targeted threat has been detected.
Keep your antivirus and Windows updates switched on so you stay protected.
