     It is said that computer viruses that cause difficulties for any users can be classified into three types; Trojan House, spyware, and Spam. A Trojan House is created to take identity 

bank- account numbers. A Spyware gathers data about the computer’s possessor. Lastly, a Spam is designed to deceive people and obtains money from them (Philpot, 2011: 47).
