I allowed those changes the first time around.... its only a temporary change... it gets changed back almost immediately.... after than i have had no more hassles with spybot, other than the initial check where it had to close the DSO exploits (AGAIN) and it came up with some active x troubles too....
But the webpage changes were temporary.... i presume they are similar to the wextrack clean 0 and wextrack clean 1 you get while installing programs...
