Computers under Attack

Computers under Attack

There are three kinds of virus  that can assault and threaten to any computer users. First, a Trojan Horse steals credit card particulars or pass code of  the bank. Second, a Spyware conceals inside a computer to gather data of computer’s  owners. Finally, a Spam is unsolicited advertising that cheats people and get money from them (Philpot, 2011:47).
