A Trojan, also known as a Trojan horse, is a type of malware that disguises itself as legitimate software. Once installed on a computer, a Trojan can give attackers remote access to the system, allowing them to steal data, install additional malware, or even take control of the computer.
There are several ways to check if your computer has been infected with a Trojan. One common method is to use an antivirus program. Antivirus programs scan your computer for malicious software and can often detect and remove Trojans.
