A Trojan Horse is a program that contain undocumented, malicious functions in addition to seemingly useful functions.

For several years, 'virus notification' e-mails have been being sent that warn of a 'brand new and dangerous' virus that can be activated just by reading an e-mail and that immediately deletes your data or formats your hard drive.
