标题: [文件操作] 批处理怎样清除cad病毒？ [打印本页]
作者: ftmm 时间: 2011-4-9 22:34 标题: 批处理怎样清除cad病毒？
以下是cad病毒代码，原文件名字叫做：acaddoc.lsp，与dwg文件放在一起的时候，autocad打开dwg文件，病毒就会被执行，感染lsp文件和mnl文件，这个两个文件都是文本方式保存。
我想请教一下，我想做一个bat来清除这个病毒，而不是简单的删除。我的思路是这样，列举出硬盘的mnl文件和lsp文件。大于200k的直接删除。
然后把剩下的mnl文件和lsp文件和一下代码对比，把相同的部分删除。以(defun s::startup (/ DOCLSP DWGPRE CDATE MAC0 MNLPTH)
为开头，最后的jjyy为结尾，中间部分清除。请问有什么思路？
我简化了一下思路，就是找到“(defun s::startup (/ DOCLSP DWGPRE CDATE MAC0 MNLPTH)
”字符串，把这个字符串以后的所有内容都删除，怎么做？用sed？

大概有30行左右，请问如何删除？

请先不要问我们的思路，你自己先把思路理好讲清楚可以？

感觉少了很多的内容。
1。想了解一下这个病毒的传播方式是不是与注册表有关。
2。感觉上你的问题很多。“好像”是不仅仅在于删除吧，如果是能否给个1234……
3。能否在需要操作的头尾作个简单的处理呢？
PS：别忘了CODE啊
