Vista Security Program Permissions

I am having a problems with installed programs having complete access in
Vista. For example, I have installed the ATI Catalyst Drivers for Vista, as
well as the Vista drivers for Creative soundcards. This is my problem;
several functions in the software are not allowed permission to run, either
because of Vista directly, or because of Microsoft Defender? In the Defender
Software Explorer folder under the heading Registry: Local Machine, several
key components for ATI and Creative are identified as "Not yet classifed,"
and do not have permission to run. With the ATI software installation the
"CLI," component is critical for running games, yet it is not allowed to run.
How do I resolve this issue? Any help would be greatly appreciated! Thank
you.
