Computers under Attack

Virus can be classified into three kinds; Trojan Horse,  Spyware, and Spam. The first kind is created to take credit card details or bank password is a Trojan Horse. The next virus type that compiles data of the computer’s owners is a Spyware. The last one that can be applied to deceive people and to get money from them is a Spam (Philpot, 2011: 47).
