cases.
Leo： I see. What shall I do if my Windows Firewall is turned off? Tony： In that case, you’d better follow these steps to enable your Windows Firewall:
1. Go to Control Panel and enter Windows Security Center 2. Click Windows Firewall 3. Select On (recommmended)
Leo： I got it. But would you please tell me more about Windows Firewall? For instance, how does it work?
Tony： Since you are so interested in this, I’d like to tell you some more details. If you run a
program such as an instant messaging program that needs to receive information from
the network, the firewall will ask if you want to keep blocking or unblock the connection.
You would see a dialogue box.
Leo： If I do want to use the program, I need to select Unblock, right? Tony： Yes, if you choose to unblock the connection, Windows Firewall will create an exception
so that the firewall won’t bother you when that program needs to receive information in the future.
Leo： I see. Thank you so much. Tony： You are welcome. 1.1
Leo： Tony，我经常听到“防火墙”一词，你能告诉我它究竟是什么吗？ Tony： 好的，没有问题。其实防火墙就是一个软件程序或者硬件设备，它可以帮助屏蔽试

图通过网络入侵你计算机的黑客以及病毒、蠕虫等恶意程序。 Leo： 看起来防火墙对于计算机系统还是很重要的。那我的系统中有防火墙么？ Tony： 如果你使用的是Windows XP（SP2），那系统中就内置了防火墙，并且默认设置下
Windows 防火墙是开启的。然而，有些情况下，防火墙可能会被关闭。 Leo： 明白了。如果防火墙被关掉了，我该怎么做呢？ Tony： 如果是这种情况，你可以这样做：
1． 进入“控制面板”，选择“Windows 安全中心”。 2． 点击“Windows 防火墙”。 3． 选择“开启（推荐）”。
Leo： 我懂了。关于Windows 防火墙你能不能再给我详细的讲解一下？比如说它是如何工 作的呢？
Tony： 既然你对此这么感兴趣，我就跟你具体讲一下吧。如果你运行一个即时通讯的程序，
这个程序需要通过网络来接收信息。防火墙就会询问你是否要“继续阻止”或者“解
除阻止”这一连接。你便会看到一个对话框。
Leo： 如果我确实需要使用这程序，是不是就应该选择“解除阻止”？
Tony： 是的，如果你选择了允许这一连接，Windows 防火墙会创建一个例外，这样一来，
以后你再实用这个程序接收信息的时候就不会受到干扰了。 Leo： 我明白了，十分感谢你。 Tony： 不客气。
Sample：1.2 Keep your antivirus software up to date
Leo： Hi, Tony, yesterday I read a magazine named PC Fans. Tony： __________It’s pretty good. Anything new?
Leo： Yes. There is an article about viruses. It lists a few primary indicators that your computer might be infected by viruses. Tony： Oh? What are they?
Leo： Well, perhaps these are the signs of viruses: 1. Your computer runs much slower than it usually does. 2. Your computer stops responding or locks up often.
3. Your computer crashes, restarts on its own and then fails to run normally. 4. Applications on your computer don’t work correctly. 5. Disk drives are inaccessible.
Tony： These are common signs of infection‐but they might also indicate hardware or software
problems that have nothing to do with a virus.
Leo： Does it mean my computer is in danger all the time?
Tony： You needn’t have to worry about it too much. Antivirus software programs can help
protect your computer from viruses. However, Microsoft Windows does not come with
any antivirus software. You must purchase and install one separately. Leo： Oh, I see. If my computer is infected by a virus, how should I remove it?
Tony： Firstly, you ought to visit Microsoft Update and install the latest updates. Then if you are
current using antivirus software, visit the manufacturer’s web site, update your software,
and then perform a thorough scan of your computer. If not, subscribe services and scan
your computer immediately. Leo： I got it. Thanks a lot.

1.2
Leo： Tony，昨天我看了一本名字叫“电脑爱好者”的杂志。
Tony： 那本杂志挺棒的。有什么新消息么？
Leo： 是的。里面有一篇文章是关于病毒的。文中列出计算机被病毒感染后的几种主要的 迹象。
Tony： 哦，都有什么啊？
Leo： 下列是你的计算机可能被病毒感染的几个征兆： 1. 计算机运行速度比平时慢很多。 2. 计算机经常停止响应或锁上。
3. 计算机崩溃、自动重启，不能正常运行。 4. 计算机上的应用软件运行不正常。 5. 磁盘驱动器无法访问。
Tony： 这些是被感染的常见症状‐这些也可能暗示是你的硬盘或软件有问题，和病毒无关。
Leo： 这意味着我的电脑就一直都有危险？
Tony： 你也不需要过分担心，杀毒软件可以帮助你抵御病毒的攻击。不过，微软的Windows
系统不自带杀毒软件，你需要单独购买并安装。
Leo： 恩，我知道了，如果我的电脑中了病毒，我应该如何移除它呢？ Tony： 首先你要去访问微软的更新网站并安装最新的更新文件。之后如果你当前使用了杀
毒软件，要访问该软件的供应商网站，更新你的软件，然后对你的计算机执行一次
全面的扫描。如果你没有使用杀毒软件，则需立即订购，并扫描一下你的计算机。 Leo： 我记住了，多谢。
Sample：1.3 Fight against spyware
Leo： I have a question to ask you, Tony? Have you ever heard “antispyware” ? Can you tell me
about it?
Tony： Yes. First of all, you should know something about spyware. Leo： Spyware? The software which works like a spy?
Tony： Oh, not exactly. Spyware is a general term used to describe software that performs certain
behaviors such as advertising, collecting personal information, or changing the
configuration of your computer, generally without appropriately obtaining your consent first.
Leo： How can I tell whether there are spyware programs in my computer? Tony： Spyware is often associated with software that displays advertisements(called adware) or
software that tracks personal or sensitive information.
Leo： Don’t you think I need to have an antispyware in my computer? Tony： Of course, that’s a good idea. Antispyware will help protect your computer against slow
performance, pop‐ups, and security threats caused by spyware and other unwanted
software. To keep up with the latest forms of spyware, you must keep your antispyware updated.
Leo： I would appreciate it if you could recommend an antispyware program, and tell me how to
use it to get rid of the spyware.
Tony： That’s not difficult. You can use Windows Defender.(Windows Defender comes with Windows Vista. If you use Windows XP SP2, you can download Windows Defender for
