问题

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。
