　　(1)對(duì)于針對(duì)谷歌 (Google Inc.)以及其他30多個(gè)公司的網(wǎng)絡(luò)攻擊，個(gè)人幾乎毫無招架之力。但對(duì)普通計(jì)算機(jī)用戶來說，只需采取一些常識(shí)性步驟即可免受病毒和其他惡意代碼的侵?jǐn)_。

　　一Install antivirus software. (2) This can protect a computer against known malicious programs that could allow a hacker to steal personal information. Cyber criminals release thousands of new programs each day so it is important to update antivirus software.

　　Be vigilant in public. Sign out of your Gmail, Yahoo or Hotmail account when using a public computer and clear the Web browser's cache, cookies and history. Then close the browser.

One way to guard against this is to encrypt important files. Also, businesses should deploy systems that track where sensitive information is being sent.

　　一Use strong passwords. Create passwords that are a mix of numbers, letters and symbols. Don't use common words or personal information. Don't use the same password on multiple sites. Put one on your cellphone.

　　使用安全密碼。使用包含數(shù)字、字母和符號(hào)的溫合密碼 g不要以常用單詞或個(gè)人信息作為密碼，不要在多個(gè)站點(diǎn)使用同一密碼，手機(jī)也要設(shè)置密碼。
