100%的中毒了或者中了流氓软件。
杀吧。

中了病毒了，试试用 AVG anti-spyware 查杀一下。

把以下文本复制保存为注册表文件，然后导入注册表中，重新启动，可以显示所有文件，你试试

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden\NOHIDDEN]

楼上正解,不过最好在安全模式下点这个文件.
倒入前把能杀掉的进程都杀掉

一定是中了病毒，确实不好杀，网上找找专杀吧。
