Windows 7: Can not install anything. Access Denied.

Can not install anything. Access Denied.

I am advanced user. Never had any problems with any Windows computers. Now I can not fix my own problem.
I can not install anything on my PC. I am allways getting errors.
For example: When I am trying to install Adobe Reader, I am getting Error 1406. Could not write value tWhiteList to key \Software\Policies\Adobe\Acrobat Reader\11.0\FeatureLockDown\cDefaultExecMenuItems.
When I am trying to install iTunes, I get error in the end (without number, just error) etc.

It makes me think, that it is not problem of software that I am installing, It is problem with Windows. I think something is wrong with permissions.


After this problem appeared, I changed Owner from SYSTEM to Administrators - no luck.
I disabled my Eset Smart Security - no luck.
I was running all setups as Administrator - no luck.
I scanned my system with Malwarebytes - nothing.
I went through many tutorials - nu luck. Mr. Google did not help.

Please, help! I am about to reinstall Windows.

Before you reinstall
Run a full antivirus scan
If you already have it run a scan with malwarebytes
Use the online eset online and run a scan

Update Malware and Eset of definitions and run in Safe mode.

If you are using a HDD then it maybe about to fall over.

It does sound like infection though.

I scanned with Malwarebytes and Eset two times.
HDD is in good condition.
Viscon, Thank you for the link, but it did not help.

Something is wrong with permissions for some reason...

If you feel that the problem is permissions this will help
Permissions - Allow or Deny Users and Groups

Ok, guys. I completely uninstalled my Eset Smart Security 8 and everything is working now. I was able to install Adobe Reader. Now I am downloading iTunes, but I have feeling, that everything will be fine.
Thank you for your help!
