This app DOES miss stuff about 20% of the time or less... BUT it's 1)free, 2)works 3) simple 4) tells you what it's going to delete 5) moves items to trash, so you can secure erase if you like...
This app DOES NOT: install system components that slow down performance (like a couple other "uninstaller/app remover" programs)... This is my choice, for the function, however, I do occasionally do a deeper manual cleaning, which may not be pragmatic for some end-users who don't know what to look for...
Just remember, the other apps that DON'T install system spy components still miss stuff...
