When was the last time you had a trained malware tech go through you system and make sure you have no hidden infections lurking in your system. If you are continuously being hacked it would signify a possible infection that is not being cleaned out.Another thing, coincidently is that my identity just got hacked into a few weeks ago and not just by one scammer/fraudster but according to my state's attorney general I have been hit by every major scam that is going on right now- lucky me!
As far as Ccleaner I wanted to make sure if you were using the registry cleaner or not and if so then no it is a problem.
