Reg Mechanic finds over 90 each time, Reg Cure finds a lot more, and yet each time I scan…there’s some left. Why are some "Free" and "The good ones" cost ? A SCAM not a SCAN !! That’s 4 questions, but the gist is there…any relative answer would be nice. Thanks !

Once the registry clean is on your computer and has found certain specific errors and gives the option to remove or clean an item–how am I to determine which item may be removed without damaging the way the computer runs. my registr scan says I have over 1200 problems! It gives the option to remove any or all of them, but warns that removing them can cause disfunction of my normal wanted programs. Should registry clean only be done by a professional? And how much would that cost?

I just want to know how to clean up a hard drive that there will no longer be any traceable info or data that can be recovered by any data recovery software.

My PC is still infected, I cannot print or update AVG 8.0 nor manualy nor automatically, other virus protection cannot detect the virus, which tools can I use to clean my PC?
