I have used Spybot-S&D for many years. I regularly update the definitions after which I immunize my computer. Today, after updating and immunizing, I still had a number of "Unprotected" items. I could not click to immunize. This has never happened before. I am the Administrator, as I am the only one on my computer. Then I did an "Undo," thinking it would reverse my latest entries. Not so, I now have at the most some 13,120 "Unprotected" items. I cannot do a re-immunization, or at the least don't know how to do it. Please help.
