what is a trojan on a computer

A Trojan, or Trojan horse, is a type of malware that disguises its true nature to trick users into thinking it's a harmless file or program. Once it infiltrates a computer, it can perform various harmful actions, such as stealing personal information, gaining backdoor access to the system, or causing damage to data or networks. Unlike viruses, Trojans cannot replicate themselves and require user interaction to be executed. They can be delivered through email attachments, free downloads, or social engineering tactics. Detecting a Trojan can be challenging, but signs may include poor device performance, strange behavior, or unexplained processes running on the device. Using antivirus software is crucial to protect against Trojans
