Recently I have run into more failing hard drives than I used to see. I run a short drive test and they pass, yet the system remains flaky even after a Tune-Up and Malware Removal. Replacing the hard drive has been the fix. For that reason I first backup most systems, unless they are really new, before I perform a Tune-Up and Malware Removal. Yes, it takes a lot of time, but that way I don’t lose my customers data! Which I really hate to do! – Joe
