Is Sim_EKB_Install_2018_08_19.exe safe?
Only MaxSecure flagged this long-observed installer with a generic label, while all 17 reporting tier-1 engines found no threat.
One of 72 engines flagged the file, and that alert came from MaxSecure using a generic trojan label. All 17 reporting tier-1 engines were silent, while static analysis found no packing or high-entropy code; however, no completed sandbox run is available.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
One of 72 engines flagged the file, and that alert came from MaxSecure using a generic trojan label. All 17 reporting tier-1 engines were silent, while static analysis found no packing or high-entropy code; however, no completed sandbox run is available.
The sole alert is MaxSecure's generic Trojan.Malware.300983.susgen label, amounting to 1 of 72 engines. No tier-1 engine detected the sample, and there is no family consensus. The executable has been observed for roughly eight years and has 19 submissions, which reduces concern that this is a newly introduced threat. Static inspection found neither packing nor high-entropy code, and researcher intelligence produced no corroborating hit. The executable is unsigned and carries a negative reputation score, but those weaker counter-signals do not outweigh the isolated low-trust detection. No completed sandbox execution or complete contacted-host reputation check is available, so runtime activity remains unverified.
What We Detected
Only 1 of 72 antivirus engines raised an alert. MaxSecure, a low-trust detector in this result set, used the generic label Trojan.Malware.300983.susgen; all 17 reporting tier-1 engines, including Avast, BitDefender, ESET-NOD32, Kaspersky, and Fortinet, reported no detection.
Threat Behavior
No completed sandbox run is available because behaviour.sandboxCount=0, so the file's runtime conduct was not observed. Static PE analysis found no identified packer, likely packing, or high-entropy code, and no independent researcher rules or known-malware records matched the hash. contactedHosts=null also means no complete host-reputation conclusion can be made.
What To Do Now
The evidence strongly favors an isolated false positive. Keep endpoint protection enabled, obtain the installer from its expected official source where possible, and verify its SHA-256 hash before execution; use additional sandbox testing if provenance is uncertain.
Where this verdict could be wrong4 caveats
- MaxSecure labeled the sample Trojan.Malware.300983.susgen, although this is one generic low-trust detection among 72 engines.
- signing.signed=false for this Win32 executable, so publisher identity and certificate history cannot support trust.
- file.reputation=-15 is unfavorable, though the payload provides no accompanying named-family or behavioral corroboration.
- behaviour.sandboxCount=0 and contactedHosts=null leave runtime activity and host reputation unverified.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Zero tier-1 detections; 17 tier-1 engines reported no threat
- Only low-trust flagging with no named-family consensus
- Observed for 2955 days across 19 submissions
- No packing or high-entropy code identified
- No CIRCL, MalwareBazaar, or YARAify corroboration
- Unsigned Win32 executable with no publisher certificate
- MaxSecure generic trojan detection on 1/72 engines
- Negative file reputation score of -15
- No completed runtime sandbox observation
- No complete contacted-host reputation result
Keep endpoint protection enabled and use a copy obtained from the expected official source. If the source or hash cannot be verified, test it in an isolated sandbox before running it.
