A Trojan, or Trojan horse, is a type of malware that is disguised as legitimate software. It is called a Trojan because it typically presents itself as something harmless, like a game or utility program, but once executed, it can perform malicious actions on the infected computer. These actions can include stealing sensitive information, downloading and installing other malware, or allowing unauthorized remote access to the computer. Trojans are often distributed through email attachments, instant messaging, and social media, and they can be very difficult to detect and remove.
