Personally, I would not use that program, because if you don't know what are you deleting, you might brick your vWii, don't delete IOS or something like that, I would use the System menu channel deleter.
The problem is these channels can't be deleted using the System Menu.
Is there an alternative to AnyTitle Deleter? Or are all programs about as equally dangerous if you don't know what you're doing. (I know the difference between IOS, channels, etc)
