Talking about Computer Viruses谈论电脑病毒
Julia: My computer crashed when I opened an E-mail attachment yesterday.
朱莉娅：昨天我打开一个电子邮件附件的时候，电脑死机了。
Sergio: It might've been infected with a virus.
塞吉奥：可能是感染病毒了。
Julia: Virus? E-mails can carry viruses?
朱莉娅：病毒？电子邮件也会带病毒？
Sergio: Viruses are most easily spread through E-mail attachments. That is why it is essential that you never open E-mail attachments unless you know who it's from.
塞吉奥：病毒最容易通电子邮件附件传播了。这就是为什么你如果不知道电子邮件的来源时千万不要打开其附件的原因。
Julia: So if I open an E-mail with such an attachment, my computer would get infected at once?
朱莉娅：那如果我打开带这种附件的电子邮件，我的电脑就会立刻受到感染，是吗？
Sergio: Well, not exactly. The E-mail itself is not a virus. A virus must be attached to the E-mail to infect an executable program. To be more exact, viruses are executable
files. Since E-mails are not system files, they cannot infect
your computer.
塞吉奥：嗯，不完全是那样。电子邮件本身并不是病毒。病毒只能附在电子邮件上以感染可执行性程序。更确切地说，病毒就是可执行性文件。因为电子邮件并不是系统文件，所以不会感染你的电脑。
Julia: But the attachment isn't like that, is it?
朱莉娅：但附件就不是那样了，对吧？
Sergio: Yes. If you download a file attached to an E-mail and run it, there is a chance that the file may contain a virus. You may try Kaspersky anti-virus software.
塞吉奥：对。如果你下载了邮件所带的附件并运行了它，那个文件就可能带有病毒。你可以试试卡巴斯基杀毒软件。
Julia : I see. Thank you very much.
朱莉娅：我明白了。非常感谢。
