AVGas still being detected into Windows Security Center

You don't need any additional programs, what you see in my image is directly in windows. Windows Start, Run and type regedit and navigate to the particular Key, right click and select permissions.

I tried it but it gives me a red warning it's impossible to do that (impossible to delete). I also tried by switching off UAC.

What red warning ?
Although I don't use Vista it might jog someone's memory and point to resolution

Are you going key by key, one by one or you're trying to delete a folder that is not empty?

I also tried by switching off UAC.

It's not a matter of UAC.

I'm going subkey by subkey, I even tried the single key, it tells me  impossible to register the modification to the permission, access refused, and upon a single key impossible to delete all the values specified (I specified only one key). I'm sorry 'cause my Gadwin Print Screen doesn't seem to print anything regarding regedit and its messages, so I can't attach any file...

Not keys but value by value...

Strange... what's up with your computer?
