My computer's antivirus system said it stopped a Trojan Horse what is it?

A Trojan Horse is a type of malicious software that disguises itself as a legitimate program to trick users into downloading or executing it. Once activated, it can steal sensitive information, compromise system security, or create backdoors for other malware. Unlike viruses, Trojans do not replicate themselves but rely on user interaction to spread. It's important to ensure your antivirus software is up-to-date and to run a full system scan to remove any threats.
