AMDDVR.exe is the RELIVE program from AMD. If you don't use that feature you can go to Task Manager and disable it. This is a previous post about how to disable the RELIVE components:

Yes, same here.
I hate to have unwanted and not installed Services running in the Background.
I have done this:
In the Taskmanager, rightclick on the Process with the amddrv.exe and select "Open Filepath"
In the Folder where both exes are, you also find the Installer (MSI) for ReLive.
Install the Service and if it's done, uninstall it and reboot your PC.
After that, both Processes were gone here (Windows 7 x64 Ultimate).
If that don't helps, stop the Services and rename the File-Extensions from amddvr.exe & amdow.exe, to amddvr.___exe & amdow.___exe.
One of the above Procedures should work.
