Spybot 2.4 white list a file

Hi,
I read in one of the forums (I can't find it now) that I could and should white list:
File:"No admin in ACL","C:\System Volume Information\SystemRestore\System Volume Information"
simply by right clicking it in the rootkit scan results.
That didn't work.
How do I white list that file?
