Hello,
What exactly did detect Spybot? Are you sure that those are items from the host list?
Spybot itself adds sites to the host file in order to block it.
By the immunization of Spybot - Search & Destroy the baddies are blocked.
That means that the sites where the baddies come from are added to the restricted zones in order to block them.
Best regards
Sandra
