标题: 高手来帮忙看看这些病毒
以下是服务器上提取出来的信息：

rc5.local文件中的内容

lrwxrwxrwx  1 root root 25 6月  30 16:51 S97DbSecuritySpt -> /etc/init.d/DbSecuritySpt

rc3.local文件中的内容
lrwxrwxrwx  1 root root 25 6月  30 16:51 S97DbSecuritySpt -> /etc/init.d/DbSecuritySpt


发作时的状态：
几秒钟内发送几十万的udp  dns请求包，目标地址8.8.8.8（好像是谷歌的dns），还会定时的往外发送少量的探测包，防火墙瞬间就瘫痪了。

查杀过程：照着上面的内容把文件都删除了，数据包暂时没发现异常，但会产生一个.ssh14（后面一大串数字）,/tmp目录下会生成跟改进程名一样的文件，并且这个进程还会不断的生成僵尸进程，并且这个进程怎么杀都杀不掉，求高人帮忙
