Is HSR_FIX.3.3D.exe safe?
Our analysis indicates this file is a benign utility, as only one low-trust engine flagged it and similar samples have been historically verified as safe.
The file exhibits no malicious behaviour in our sandbox and lacks consensus from high-trust antivirus engines. The single detection is attributed to a low-trust heuristic engine, which is consistent with common false positives for this type of utility.

Before running
Run it only when it came from the developer's official site or another source you independently trust.
If you already ran it
Keep normal device protection enabled and stop if the file behaves unexpectedly.
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.
The file exhibits no malicious behaviour in our sandbox and lacks consensus from high-trust antivirus engines. The single detection is attributed to a low-trust heuristic engine, which is consistent with common false positives for this type of utility.
The file is a common, older utility with no high-trust engine detections. The single malicious flag comes from a low-trust engine, which is a frequent pattern for benign software. Sandbox analysis confirms the absence of offensive techniques, and similar files sharing the same import hash have been previously cleared. We conclude the detection is a false positive.
What We Detected
Our analysis of 75 antivirus engines shows only one low-trust detection (APEX). No high-trust engines (tier-1) identified any malicious activity, and there is no consensus on a threat family. The file is unsigned, which is common for this category of software.
Threat Behavior
The file was executed in a controlled sandbox environment. It performed 11 ambient system operations but triggered zero offensive MITRE techniques. While a heuristic rule regarding direct IP connections fired, this is common in legitimate installers and does not indicate malicious command-and-control activity in this context.
What To Do Now
The evidence suggests this file is safe to use. Ensure your endpoint protection remains active to monitor for any unexpected changes, but no specific remediation is required for this file.
Where this verdict could be wrong2 caveats
- The file is unsigned, which prevents definitive publisher verification and increases the risk profile compared to signed software.
- The 'MalwareTips.Synth.DirectIpC2' heuristic fired due to direct IP connections, which could theoretically mask malicious activity if the infrastructure is compromised.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/17 tier-1 engines flagged
- 0 offensive MITRE techniques
- similar hashes previously verified as safe
- common prevalence (300 submissions)
- unsigned executable
- direct IP connections observed
The file appears to be a legitimate utility. Keep your endpoint protection enabled as a standard security practice.

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
Behavioral heuristics matched patterns associated with malware. Corroborating evidence determines how much weight they carry.
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.

Section entropy & packers
No high-entropy executable section or known packer signature was detected. Data and resource sections can still have high entropy without indicating packed code.
How widely this file has been seen
Widely seen in the wild for a long time. High prior this is legitimate; isolated detections on common-old files are usually false positives.
