Windows 7 Home Premium Group Policy virus

On a Windows 7 Home Premium system that has not been maintained, we have the "This program is blocked by group policy, contact the system admin."

We get this message on every attempt to install cleaners, and virus killers including Malwarebytes, C Cleaner, ADW Cleaner, etc..  We can download the programs but will get the message when we try to install.

Many of the already installed system tools are blocked as well.

We have found several "fixes" on Google including editing the registry.  None of them work.

Any help would be appreciated.

I would run chameleon and combofix from safe mode. Those should get you going. Also try making malwarebytes a portable app which gives you a better chance at running it.
