求一篇英语作文,150词左右.题目是“The disadvantage of personal investigation”.语法最好高级点.
1.The first disadvantage when using the Internet is that your personal information is not safe,especially important one.In fact,as you surf the web,read emails,download softwares or even chat with your friends,a Trojan,known as a hidden program,can be sent to your computer without your knowing.It will steal and transfer all the information you save to the sender.This person,after that,may make use of or give it to somebody else.For example,if you use Internet to shop online,your credit card number can be stolen,and then the money in your bank account will probably be used up.Or if you send some confidential material to your business partners,your opponents may try to steal it and harm your company.The last con is virus threat.What is a virus?A virus is nothing but a program which disrupts the normal functioning of your computer systems.Computers attached to internet are more prone to virus attacks and they can end up into slowing down your computer’s speed,destroying data and crashing your whole hard disk.Maybe most of us here have at least once suffered from viruses no matter how hard we have tried to prevent them from infecting the computers by using some anti-virus programs.So we should know clearly that they cause bad damages ,but are inevitable.
