Trojan.Win32.SEPEH.gen Detection & Removal
Trojan.Win32.SEPEH.gen is a detection designator assigned by antivirus applications to a suspicious file.
There is a possibility that the file flagged as Trojan.Win32.SEPEH.gen is indeed a Trojan horse. Trojans are a type of malware that can perform a range of malicious functions on a victim system, ranging from spying on the user to exfiltrating data from the system and performing file operations.
However, the string ".gen" at the end of the detection means that this is very likely a "generic" detection. A lot of those detections are driven by heuristic analysis. In very simple terms, this can mean the antivirus software only suspects the file is malicious and has flagged it just to be on the safe side.
In most cases, it's not worth it to allow or run a file that has triggered any sort of detection, following suit with the antivirus app and just staying on the safe side.
If you have any doubts about the file, it is always better to quarantine or delete it once the anti-malware application has flagged it. If you really must use the file, it would be best to scan it with at least one other antivirus app or upload it to an online service that can do this for you.
