A Trojan Horse Virus is malware that allows unauthorized access to your system. This virus is designed by hackers to use a target computer for data theft, installation of unauthorized software, modification of other software running on your computer, deleting useful files and so on. These viruses allow the hacker to essentially control the user computer.
A Trojan horse virus can be installed through downloaded software, from file sharing networks, email attachments, or from other sources. A Trojan horse virus differs from other malware in that it appears to be legitimate software, but once installed make changes on your computer. The changes may vary from harmless icons appearing on your desktop to serious damage to your computer. Unlike other viruses and worms, these do not self-replicate.
