很多时候系统出了问题可以运行 sfc /scannow 来修复，不过这里推荐一个比 sfc 更好的命令，可以基本把木马、病毒修改的系统文件都列出来：
sigverif.exe
我的系统里这些文件被修改过：
tcpip.sys 下BT用的破解 SP2 连接数
taskmgr.exe 我用的是Longhorn版的，可以看进程启动的参数～～
uxtheme.exe 这个是非官方桌面主题的破解
大家也扫一下，当你会发现有多少程序修改了你的系统，你会吓一跳的
可以用msconfig来还原被修改的系统文件
Many times when there are system problems, you can run sfc /scannow to repair, but here is a recommended command better than sfc, which can basically list the system files modified by trojans and viruses:
sigverif.exe
The following files in my system have been modified:
tcpip.sys for the cracked SP2 connection limit used by BT
taskmgr.exe I am using the Longhorn version, which can view the parameters of process startup ~~
uxtheme.exe This is the crack for unofficial desktop themes
Everyone also scan, and when you will find how many programs have modified your system, you will be surprised
You can use msconfig to restore the modified system files
