i have avg installed on a system along with ccleaner, cleanmypc, wise registry cleaner and comodo system utilities. (for testing purposes) the result from registry scanner on each app are: -pc analyzer = 1,099 -wise registry cleaner = 21 -ccleaner = 75 -comodo system cleaner = 220 (in-depth) -cleanmypc = 81 now my question is avg pc analyzer have found a significantly higher number of entries but can it really be trusted? wont it just make the system unbootable? are these really unnecessary entries? are there any reviews of the pc analyzer? any comments are welcome.
