A **, sometimes referred to as a ** horse, is non-self-replicating malware that appears to perform a desirable function for the user but instead facilitates unauthorized access to the user’ computer system. The term is derived from the ***** horse story in greek mythology.
A computer virus is a computer program that can copy itself and infact a computer. A true virus can only spread from one computer to another.
The chief difference between a ** horse and a virus is that a ** horse does not replicate itself. A virus does.
