2. WHAT IS TROJAN HORSE?
A destructive program that
masquerades as a benign application.
Unlike viruses, Trojan horses do not
replicate themselves but they can be just
as destructive. One of the most insidious
types of Trojan horse is a program that
claims to rid your computer of viruses but
instead introduces viruses onto your
computer.
