ACL Errors, Can't Running Any Windows Program (such cmd, taskmgr, etc)

Today I got weird Problem, My Windows 7 Ultimate eventually can't execute any Windows Programs, such : Msiexec, Cmd, Notepad, Taskmgr, Msconfig, Regedit, etc.
When I tried to run any Windows Programs, the Message Box Appeared with this message : Insufficient system resources exist to complete the requested service.





Then I checked my System32 Directory, I was shocked because All of Windows Defaults Programs appeared with Locked Icon.


Then I checked 1 by 1 Windows Program, for an Example : dcdiag.exe.

I checked the Security Tab and I got this notifications : No Permissions have been assigned for this object.
Warning : This a potential security risk because anyone who can access this object can take ownership on it. The object's owner should assign permissions as soon as possible.



Other Informations :

1. My Windows account Privilege is Administrator.
2. I've Actived Anti-Virus and Always Updated.
3. In Safe Mode Everything Was Fine, I Can run Notepad, Task Manager, Command Prompt, etc (except : Msiexec / .msi Installer).
4. I tried System Restore in Safe Mode, but I don't have any Restore Points. In Normal Mode, I can't execute System Restore.

So, How can I solve this Problem?

I'm using Avira Free (Always Turned On & Updated).
I guess It wasn't caused by Malware.
