that will not delete necessary files, passcodes and good things but get rid of bad if you dont know much about computer. I need a free and safe one
I have windows xp, a dell computer, commodo, esquared, yahoo antispy.

My computer freezes up to hundreds of times a day, crashes and is real slow.

I tried deleting big files, scans,. defrag, disk clean up and scanned and did recovery of disk errors.

None of that helped. I put off registry cause I heard if you aren’t computer proficient you can mess up your computer. Is this true and any safe for newbies free registry cleaners or what else might help with these problems..using the computers has become frustrating with all these freezes.
