A Trojan horse, in computing, is a type of malicious software that is disguised as something useful or desirable. Once installed, it can give an attacker access to your computer or network.
Trojan horses can be used to install other types of malware, including ransomware, keyloggers, and spyware. They can also be used to steal information or to damage your computer or network.
The best way to protect yourself from Trojan horses is to keep your software up to date, be suspicious of unsolicited messages and attachments, and use a good antivirus program.
