服务器80端口被恶意流量拥塞，怎么解决？
大家好，下面这种问题怎么解决？iis日志里面出现下面这种情况，我觉得可能是服务器中了恶意流量拥塞的毒了，导致网站访问很慢，cpu占用情况正常，低于5%。内存使用也正常。日志中显示，总是持续访问某个根本不存在的文件，现在根本就没有local这个目录存在，并且客户端ip地址总换。以前某些网站文件没有设置成只读，总是被篡改网站文件，后来用备份的文件还原后，都弄成只读的，才解决了被篡改文件的问题，但是从外部访问网站的速度很慢，用360杀毒杀不出来。以下是部分日志，这样的日志很多：

比如，10秒内同一个地方请求同一资源超过20次就拒绝他的请求10分钟. --------------------编程问答--------------------
