Suggest that you...
(1)first delete the driver file you downloaded, then
(2)immediately uninstall that driver set, and after that
(3)go to C:\program files (x86) and delete the entire AMD directory, if it still exists. Then
(4) run defender on your C:\ drive to make sure the source is gone. After that
(5) redownload the drivers from the official AMD site--not from a 3rd-party site. And then
(6)reinstall the drivers and see how that goes.
