Keep it clean. On a PC, run Disk Cleanup and Disk Defragmenter at least once a month. This will store files more efficiently so your system doesn’t slow down. After about four years, your computer is elderly. If you’re shelling out for a blazing-fast Internet connection, pony up for a new model.

Check the cables. “People are always shocked that a cable came loose,” says Geek Squad agent Derek Meister. Of course, everything that needs power is plugged into an outlet, right?

Got neighbors? If you do, protect your home wireless network with a password. “If a person knows what he’s doing, getting into a computer on a non-encrypted net-work is easy,” says Schildkraut.

You backed up your data, right? External hard drives with lots of memory now sell for under $200, and automated programs like Cobian Backup or Apple’s Time Machine make regular backups a no-brainer. Secure online backup services save your data offsite should anything happen to your home.

If you travel with your laptop, get a lock. A 2007 survey by the Computer Security Institute found that 50 percent of respondents had a laptop or other mobile device sto-len in the past year. A simple cable lock (starting at about $20) lets you physically secure your laptop anywhere you go.

Remember: If your company owns the computer, they own what’s on it, too—even your email in some cases. Act accordingly.

1.保持清洁。在个人电脑上，每月至少运行一次磁盘清理和磁盘碎片整理程序,这将更有效地存储文件确保您的系统不会慢下来。大约约四年后，您的计算机就上年纪了。如果您还保持了一个高度的上网热情，掏腰包里买个新的吧。

2.检查电缆。 奇客队（Geek Squad ）的代理商Derek Meister（德里克-梅斯特）说“人们总是对一个变得松散了的电缆感到震惊， ”当然了，这一切都需要电源插入插座，对不对？

3.有人入侵？（据windrose译友下同，Got neighbors?，直译为：有邻居来？）如果你这样做，设密码保护您家庭的无线网络。Schildkraut（希尔德克劳特） 说 “如果一个人知道他在干什么，进入一个没有加密的网络计算机是很容易的， ”

4.您备份您的数据，对不对？现在有大量内存的外置硬盘售价不足200美元，和自动程序像Cobian（档案资料夹& BitComet --比特彗星)备份或苹果的时光机进行定期备份是无需动脑筋的事物。安全的在线备份服务保存您的数据离线你家可能发生的任何事情。

5.如果您带着您的笔记型电脑旅行，买把锁。 一份计算机安全研究协会2007年的调查发现，有50%的受访者在过去的一年里有笔记本电脑或其他移动设备被偷。一把简单的铁锁（大约20美元起步）可让你带着身体安全的笔记本电脑去任何地方。

6.记住：如果电脑属于你的公司，那么其中的内容也是属于公司的 —— 在某些情况下即便你的电邮也是（属于公司的）。

7.请记住：我们没有编造这个问题，我们只是想帮助你解决它。
