Javascript写了一个清除“logo1_.exe”的杀毒工具（可扫描目录）
最近我的共享目录里面所有exe文件都被病毒感染，上网一查才知道是“logo1_.exe”这个咚咚搞的鬼。网上对这个病毒的危害性评价得很高，认为只要中了病毒，整台机器都只能“Format”了。其原因大概就是因为所有应用程序都被感染，运行任何程序都回使病毒“重生”。我使用“卡巴司机”杀毒，结果提示无法清除，将我整个exe文件给删了。郁闷中，自己动手写了这个咚咚来清除已感染程序里的的病毒。
中了“logo1_.exe”病毒请上网查找相关清除方法，本工具只是清除被感染文件里面的病毒，因没有太多时间，没做
注册表自动恢复功能；)
中毒的现象：会在所有含有exe文件的目录下建立一个隐藏的“_desktop.ini”文件，里面记录了病毒感染的日期。如果删除该文件，病毒会重复感染已感染的应用程序并重新生成“_desktop.ini”文件；很多被病毒感染的应用程序会出现很模糊的ICO图标。
网上传说该病毒每三分钟活动一次哦，还说新装的机器在带毒的网络工作，三分钟之内就会被遭毒手，装新系统的朋友小心了。
为防止不小心的朋友运行病毒文件，我已经将“.exe”后缀去掉了。大家可以添加“.exe”后缀名对比杀毒前和杀毒后的ICO图标变换情况。
再次提醒：未使用本工具清除“病毒样本”里的病毒之前，千万别运行“病毒样本”程序。否则马上中标 ：D
