Horse
Like the fabled gift to the residents of Troy, a Trojan Horse is an application
designed to look innocuous. Yet, when you run the program it installs a virus or
memory resident application that can steal passwords, corrupt data, or provide
hackers a back door into your computer. Trojan applications are particularly
dangerous since they can often run exactly as expected without showing any
visible signs of intrusion.
