Or any other optimizer/diagnostic tools? I have all the IMO best spyware scanners/protection but still I like to keep my PC in as best health as possible. I've had 4 or 5 crashes in the last couple of days, as well as restart problems I've had for quite a while. I looked on the CNET download website last night for a program that would clean out the registry and get rid of junk files etc AND is spoken highly of by all reviewers. I found Tune Up Utilities and it seems everyone who uses it loves it. Upon doing the registry cleaner it found HUNDREDS of outdated entries. I'm extremely cautious about deleting this kind of stuff so only delete stuff I'm absoloutely positive I don't need. It also defgrags the registry. Seems an excellent program from what I've seen so far. Are there any other users out there, and if not what optimizers/diagnostics/system utilities do you use? I, for one would be open to any recommendations.
