Personally, having just downloaded the earlier version of 'KIES'
for my mobile S5, I'd recommend 'Revo-Uninstaller' the 'PRO
version ( it costs money but there is a free version ) ;
'C Cleaner' is also good at cleaning the REGISTRY out,
but events in early September 2017 ( malware found inside
'C Cleaner' mean that none of these can be trusted 100% :
I recommend using various 'non-autorun' Anti-Virus programs,
as well as 'MSIE' ( which isn't particularly good at finding malware ).
