A Trojan horse or Trojan is a malware, which is malicious software that performs self-replications by inserting its code into the other programs. Trojan is coined after the “Trojan horse” in Greek mythology. A large wooden horse was made in the name of peace towards the Trojan and Troy which had thousands of hideous soldiers inside it, who would later invade overnight and capture it. Similarly, Trojan intends to disrupt damage, steal or perform harmful action to the network or data. This malware tricks computers and seeks to deceive the network into loading and to execute the malware on the device. After the installation, it can perform the action it was designed to do. Trojan sometimes misinterprets as a virus, but it is not as viruses can replicate themselves, but Trojan fails to do so. Someone has to execute it. If you somehow have also been a target of the hackers, you must approach a reliable cyber security expert like BITS.
