After taking more than 30 minutes which it says only takes 10 minutes the system get stuck. I have restarted the system after an hour or so on stalled condition.Still 100% though.Do I have to run Combofix again
 
After several attempts with Combofix, it didnt go beyond a certain point. I have manually deleted the Advanced SystemCare Ultimate, even its registry components but Combofix is still showing its warning.
