问题解决--网络上的病毒该怎么防范呢

<P class=MsoNormal style="TEXT-INDENT: 21pt"><SPAN style="FONT-FAMILY: 宋体; mso-ascii-font-family: &#39;Times New Roman&#39;; mso-hansi-font-family: &#39;Times New Roman&#39;">网络病毒通常是指特<SPAN class=GramE>洛</SPAN>伊木马和邮件病毒，因为是通过网络传播的，所以称为“网络病毒”。</SPAN> <SPAN style="FONT-FAMILY: 宋体;

mso-ascii-font-family: &#39;Times New Roman&#39;; mso-hansi-font-family: &#39;Times New Roman&#39;">邮件病毒和普通病毒是一样的，只不过由于它们主要通过电子邮件传播，所以才称为“邮件病毒”，一般通过邮件中“附件”夹带的方法进行扩散，一旦你收到这类</SPAN><SPAN lang=EN-US>E-mail</SPAN><SPAN style="FONT-FAMILY: 宋体; mso-ascii-font-family: &#39;Times New Roman&#39;; mso-hansi-font-family: &#39;Times New Roman&#39;">，运行了附件中的病毒程序，就能使你的电脑染毒。这类病毒本身的代码并不复杂，大都是一些脚本，比如</SPAN><SPAN lang=EN-US>I love you</SPAN><SPAN style="FONT-FAMILY: 宋体; mso-ascii-font-family: &#39;Times New Roman&#39;; mso-hansi-font-family: &#39;Times New Roman&#39;">病毒，就是一个用</SPAN><SPAN lang=EN-US>VB Script</SPAN><SPAN style="FONT-FAMILY: 宋体; mso-ascii-font-family: &#39;Times New Roman&#39;;

mso-ascii-font-family: &#39;Times New Roman&#39;; mso-hansi-font-family: &#39;Times New Roman&#39;">并打开附件后，病毒就会按照脚本指令，将浏览器自动连接上一个网址，下载木马程序，更改一些文件后缀为</SPAN><SPAN lang=EN-US>.<SPAN class=SpellE>vbs</SPAN></SPAN><SPAN style="FONT-FAMILY: 宋体; mso-ascii-font-family: &#39;Times New Roman&#39;; mso-hansi-font-family: &#39;Times New Roman&#39;">，最后再把病毒自动发给</SPAN><SPAN lang=EN-US>Outlook</SPAN><SPAN style="FONT-FAMILY: 宋体; mso-ascii-font-family: &#39;Times New Roman&#39;;
