Many spyware scanners aren't programmed to be aware of certain entries in the restricted sites list. Some need to catch up/be updated to ignore them. I never pay any attention to a scanner finding something in the restricted zone/zonemap/domains because I know they've been placed there on pupose by progs like spybot, iespyad, spywareblaster etc... I'd only be concerned if I did a hijackthis scan and found something bad in the trusted zone.
