均在命令行下使用
antiiframe.vbs
#该脚本是批量挂马程序的逆向，用于批量清除被添加到文件中的恶意代码。记事本打开文件可以修改pattern参数指定要处理的文件名，文件名之间用|隔开（也支持vbs正则表达式）。由于要修改文件，请谨慎的使用（最好先备份文件）
#用法: cscript antiiframe.vbs [处理的路径] [包含清除内容的文件]
#例子: cscript antiiframe.vbs d:\web d:\lake2.txt
----------------------------
scan.vbs
#该脚本用于本地扫描asp木马，速度比asp版快很多。可能存在误报、漏报的情况，视具体情况处理
#用法: cscript scan.vbs [扫描路径] [结果htm文件路径]
#例子: cscript scan.vbs d:\web f:\my\report.html
