昨天帮邻居小平家电脑杀毒。打开电脑随便看了下，感觉反应速度很慢，尤其是IE，不是一般地慢。打开任务管理器就看到logo_1.exe进程，又是它！前些天在学校帮小芳姐电脑杀毒时也是这个病毒，记得当时她电脑除了C盘以外其它盘都无法双击打开，现在小平的电脑也不例外。不过这个不难，我在DOS下删除autorun.inf和对应的病毒文件，过了会它又在根目录下自动生成。我写了几句简单的批处理，就轻松将其彻底删除而无法再自动拷贝进来。logo1这个病毒我不是很熟悉，不过我结束它的进程后，在C盘找到它的主文件，轻松删除之。我检查了它的启动项和服务，才发现已经被搞得乱七八糟，我一一将它们删除或修复。后来我才知道她的电脑上中了logo1、灰鸽子和落雪三种病毒，都是非常常见的。电脑情况是好多了，不过这个病毒这么频繁，我得去网上找下资料学习一下。

　　被我Down了个logo_1.exe病毒专杀工具和免疫补丁，打开一看，居然是两个批处理和一个注册表文件。
打开KillLogo1.bat，内容如下：

@echo off

if exist %windir%\rundl132.exe echo 发现威金!

pause

taskkill /f /im rundl132.exe
taskkill /f /im logo_1.exe
taskkill /f /im logo1_.exe

　　原来这么简单的一个批处理就可以称为专杀工具了，只不过就收集了几个常见的logo1病毒的文件名而已。不过logo1本来就是蠕虫病毒，特点应该是大范围传播，而不是顽固型的。
这样的一来，我想写个免疫补丁也就不难了。打开Logo1免疫补丁.bat，内容如下：
