已经在安全模式下，关闭了系统还原，杀了一下毒，没有找到病毒，但是用木马克星扫描：C:\WINDOWS\svchost.exe 怀疑为木马.
C:\WINDOWS\system32\cns.dll 怀疑为3721广告
C:\WINDOWS\system32\cns.dll 怀疑为CNNIC广告
C:\WINDOWS\system32\cns.exe 怀疑为baidu广告
C:\WINDOWS\system32\cns.exe 怀疑为CNNIC广告
C:\ 扫描完成.
还是有C:\WINDOWS\svchost.exe ，但是我在C:\WINDOWS怎么找不到svchost

另外请问系统还原与ghost还原系统有什么不同，ghost还原系统需要光盘启动吗？
