All registry cleaners claims are false. I have AVG Anti- Virus which is one of the best on the market, AVG PC Tune Up and Spybot. After a full cleaning and you run one of these other super duper reg cleaners it still comes up with 500-**** things that need to be cleaned up. 95% of PC cleaners are garbage and take your money laughing there way to the bank. Spybot is practically free if you want to donate and most clean ups you can do yourself. AVG & AVG PC Tune Up is the best way to go and cost worthy.
