中了个病毒，不知道叫什么名字，电脑工作效率变慢，蓝底色桌面变成黑底色。上面有英文，最上面是黄色的英文WARNING！下面题目是YOU`AR IN DANGER 内容如下：
 
                          WARNING!
                      YOU'RE IN DANGER!



ALL YOU DO WITH COMPUTER IS STORED FOREVER IN YOUR HARD DISK. WHEN YOU VISIT SITES, SEND EMAILS... ALL YOUR ACTIONS ARE LOGGED. AND IT IS IMPOSSIBLE TO REMOVE THEM WITH STANDARD TOOLS. YOUR DATA IS STILL AVAILABLE FOR FORENSICS. AND IN SOME CASES FOR YOUR BOSS, YOUR FRIENDS, YOUR WIFE, YOUR CHILDREN.

Every site you or somebody or even something, like spyware, opened in your browser, with all images, and all downloaded and maybe later removed movies or mp3 songs - ARE STILL THERE and could broke your life!


SECURE YOURSELF RIGHT NOW!
REMOVE ALL SPYWARE FROM YOUR PC!

并且，电脑右下角的工具栏出现一个黄色 中间带有黑色感叹号的三角。

请高手来帮我杀掉这个东西。再次跪拜ING~~~~~~~~~~~~~~~~~

点击黑色部分和文字会出现一个新的网页,网页地址和内容现在还没看到,因为一出现这个新网页,就无响应,然后就死机.

5楼的高手，我已经把LOG贴出来了，请问要如何解决？

我的电脑是2000系统，在清理3721的时候遇到了问题，请问，如何在硬盘上删除以下内容？（以下引用的是3721的卸载办法的后半部分）

在删除完注册表中的项之后，还需要删除存储在硬盘中的3721网络实名文件。
　　删除如下文件：
　　C:WINNTDOWNLO~1 目录下
　　（如果是win98，这里的 C:WINNTDOWNLO~1 为 C:WINDOWSDOWNLO~1 下同）
2001-08-09 15:34
3721
2001-08-02 17:03 40,960 cnsio.dll
2001-08-08 14:14 102,400 CnsMin.dll
2001-08-24 23:14 42 CnsMin.ini
2001-08-09 10:18 13,848 CnsMinEx.cab
2001-07-06 17:57 32,768 CnsMinEx.dll
2001-08-25 02:52 115 CnsMinEx.ini
2001-08-25 02:51 17,945 CnsMinIO.cab
2001-08-02 17:02 32,768 CnsMinIO.dll
2001-08-24 23:15 40,793 CnsMinUp.cab
C:WINNTDOWNLO~13721 目录下
2001-08-02 17:03 40,960 cnsio.dll
2001-08-24 15:53 102,400 CnsMin.dll
2001-07-06 17:59 213 CnsMin.inf
2001-08-24 15:48 28,672 CnsMinIO.dll
　　以上文件全部删除，这样3721网络实名“病毒”就从您的计算机中全部清除了。
　　最后，重新启动计算机，进入正常模式。现在已经完全没有3721网络实名的困扰了！

找不到这个目录

命运里の金色 ,我已经按你的方法做了，可是仍然无法删除那流氓软件。
