问题 WASHINGTON -- considering the serious warnings lately about Internet viruses(病毒), users may don’t use their machines just to keep them safe. In reality, common sense and a few basic tips can keep Internet surfers secure.
   Anti-virus software is a must, and it should be updated at least once a week to recognize newly viruses. If this is not done, you will meet great troubles.
   People with broadband Internet connections should have also a firewall. These protect the computer from attacks by hackers(黑客).
   Then it is time to think about computer habits. Unlike old viruses, which spread only through shared disks, the Internet brings viruses straight to the e-mail box. ff an e-mail with attachment(附件) comes from an unknown sender, or unexpectedly from a known’ sender, it should not be opened.
   On receiving an unexpected attachment from a friend, experts suggest a telephone call to make sure of the mail’ s source before opening. If you open the mail without any consideration, you will be easily attacked by the hackers. [br] Which of the following is NOT right according to the passage?
选项 A、Something can be done to keep our computers safe.
B、Even an e-mail attachment coming from a friend may not be safe to open.
C、We should not use our computers to defend ourselves from viruses.
D、Anti-virus software made some years ago is hard to protect today’s computers.
答案 C
解析 判断推理题。选项A、B、D的内容在文章中均有体现，可是选项C是荒谬、错误的。我们按照基本的常识就可以将它排除。计算机不能因为有感染病毒的可能，就关机不再用了。所以正确的答案为C。
