第25篇 保护个人计算机安全的技巧对于针对谷歌以及其他30多个公司的网络攻击，个人几乎毫无招架之力。但对普通计算机用户来说，只需采取一些常识性步骤即可免受病毒和其他恶意代码的侵扰。安装杀霉软件。这样可将已知恶意程序拒之门外，以防黑客窃取个人信息。网络罪犯每天发布数千个新程序，因此及时更新杀毒软件十分重要。安装软件补丁。微软和奥多比系统公司等公司均不断发布小的的更新程序以修补Windows操作系统和 PDF reader程序中新发现的安全漏洞。用户应当及时安装这些补丁。保持戒心。除非确保安全无毒，否则一律将电子邮件附件、社交网站链接和网站上的可下载文件视同病毒处理。这些是罪犯将恶意软件传送到受害者计算机的最常用伎俩。在公共场合保持警惕。用公共计算机登录Gmai1、雅虎或 Hotmail邮箱后应登出，清空浏览器缓存、 cookie和历史。
