我每安装一个文件他总是非法操作~~然后装好后打不开这个软件（无论装什么）只有重起后才能用！而且机器老是好卡，可是我用木马杀客和卡吧杀都查不出，到底怎么会事，YLIVE是不是病毒呢？
我不知道我这样说你能不能帮我解决！！谢谢
而且我机器老是暴卡，老是停止响音，我刚重装过系统可还是这样，昨天居然卡了下，重起机器RUNDLL文件找不到了~~~我到底中了什么毒啊，我怎么查不出呢，麻烦你

飞跃迷离，斑竹帮帮我，谢谢

这是我的日记，不知道有没有什么病毒的东西呢

建议用sfc命令检修系统文件看看
Win98: 开始-->程序-->MSDOS方式
Win 2000/xp:开始-->程序→附件→命令提示符
键入“sfc /scannow”，按下回车键后，“系统文件检查器”就会开始检查当前的系统文件是否有损坏、版本是否正确，如果发现错误，程序会要求你插入Windows 安装光盘来修复或者替换不正确的文件。

我是WIN ME的，我进入了DOS下，在我打入C：\>sfc/scannow他提示我这个命令不对饿，斑竹

建议把“雅虎助手”卸载看看...
