Trojan.Heur!.01212023

Malware family: Heuristic

Heuristic detection uses behavioral analysis and pattern recognition to identify potential threats without specific signatures. This proactive approach detects suspicious code behavior that may indicate malware presence. Detection may occasionally produce false positives when legitimate software exhibits similar behavioral patterns.
