Spybot recently gave me multiple pop-ups reporting changes in my registry, I accidentally clicked 'accept' instead of 'deny' on these. Fortunately, I checked the box that says to 'remember the change', but I have no idea how to access that and reverse the changes now. Also, how is one to know what constitutes 'dangerous' registry changes and which changes are 'O.K.'? Thanks to whomever can help me with this!
