我的电脑最近刚重装过，发现开机后有个进程cmd.exe[非命令提示符进程，用msconfig没发现]，占用CPU50以上，随之系统进程csrss.exe占用30-40，如果结束掉cmd.exe后csrss.exe的CPU占用率又回复正常。。。还有就是打开QQ后发现多了个myqq_.exe的进程，在SYSTEM32下面发现了myqq_.exe和qq_mail.dll等，不知这个是否是病毒。。
我退到安全模式下进注册表编辑器中没找到可疑的cmd.exe的项，在搜索文件时发现了SYSTEM32下有个hkcmd.exe，但杀掉后重启还是有cmd.exe。。。我的电脑经常要写程序，搞教学，非常重要，恳求各位帮帮忙杀掉这个万恶的东西
