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.

    Please remember: We didn’t create the problem; we’re just trying to help you fix it.

    1.保持清潔。在個人電腦上，每月至少運行一次磁盤清理和磁盤碎片整理程序,這將更有效地存儲文件確保您的系統不會慢下來。大約約四年后，您的計算機就上年紀了。如果您還保持了一個高度的上網熱情，掏腰包里買個新的吧。

    2.檢查電纜。 奇客隊（Geek Squad ）的代理商Derek Meister（德里克-梅斯特）說“人們總是對一個變得松散了的電纜感到震驚， ”當然了，這一切都需要電源插入插座，對不對？

    3.有人入侵？（據windrose譯友下同，Got neighbors?，直譯為：有鄰居來？）如果你這樣做，設密碼保護您家庭的無線網絡。Schildkraut（希爾德克勞特） 說 “如果一個人知道他在干什么，進入一個沒有加密的網絡計算機是很容易的， ”

    4.您備份您的數據，對不對？現在有大量內存的外置硬盤售價不足200美元，和自動程序像Cobian（檔案資料夾& BitComet --比特彗星)備份或蘋果的時光機進行定期備份是無需動腦筋的事物。安全的在線備份服務保存您的數據離線你家可能發生的任何事情。

    5.如果您帶著您的筆記型電腦旅行，買把鎖。 一份計算機安全研究協會2007年的調查發現，有50%的受訪者在過去的一年里有筆記本電腦或其他移動設備被偷。一把簡單的鐵鎖（大約20美元起步）可讓你帶著身體安全的筆記本電腦去任何地方。

    6.記住：如果電腦屬于你的公司，那么其中的內容也是屬于公司的 —— 在某些情況下即便你的電郵也是（屬于公司的）。

    7.請記住：我們沒有編造這個問題，我們只是想幫助你解決它。
