自中了dwon病毒以来，系统进程就多了个cmd，往往是在开机10分钟左右出现，占用CPU不断增加，最后能达到100，系统很卡，但结束掉后就不卡了，我用瑞星，卡卡，流氓软件清理助手，360卫士，杀了n遍已经杀不出什么了，可cmd还是出现，怎么回事，请高手指教

下载sreng2.zip 0.4MB 系统扫描工具，解压，打开，运行，执行扫描，保存日志，将日志内容贴上来，注意不要改动，一次贴不完，分多次贴！扫描前关闭所有手工打开的软件和窗口!

32下的应该是正常的,不过如果不你启动命令行,应该不会出现那个进程.除非是用它调用了动态链接库文件.

32下的文件不一定都是正常的，也有可能是病毒，
楼主，你不是知道文件名吗，
进入安全模式去搜索，找到就删，
还有，最好是记住它的日期，然后再用日期搜索一下，
看看还有哪些文件是跟它一起进来的，注意自己分析一下，
哪些是自己的，哪些是跑进来的，
要是能确定，就直接删掉。

找到就删?!
CMD.EXE都是系统里的正常的可执行文件!
cmd.exe
进程文件： cmd 或者 cmd.exe


进程名称： Windows Command Prompt
 
描述：
cmd.exe是微软Windows系统的命令行程序，类似与微软的DOS操作系统。cmd.exe是一个32位的命令行程序，运行在Windows NT/2000/XP上。这不是纯粹的系统程序，但是如果终止它，可能会导致不可知的问题。
