Clean It Time

Is there a program like Norton 360 or something that fixes registry errors, can clean and fix errors in the hard drive, and all those sorts of things? I already have Norton Anti virus, so that isn’t really necessary, but if it comes with anti virus that is better than Norton, all the better. I’m just sick of looking for free online programs that fix errors and clean everything. I don’t really know much about Norton 360, but there is also Norton System utilities, which has some of the stuff 360 has but 360 is missing some of the stuff fro utilities. Isn’t there a really good program that has most of the things i would need in a nice package? Like a registry cleaner, maybe defragger, temporary files cleaner, you get the point. I just want to know what is what and what i should clean and everything, and obviously no free program can do this well enough. (also, maybe benchmarking?)oh yeah, and im poor so try to recommend stuff under $100 if you can. Thank you so much and i appreciate any help at all.
i have anti-virus, i am not really looking for a new one, that is not the priority!

I keep my computer clean, neat, and virus free with three freeware programs that you can download super-fast.
First, I use ZoneAlarm as my antivirus because it asks me about any program that attempts to access my network or internet. It can be found here:

Second, I use Malwarebytes Anti-Malware to scan for spyware every now-and-then. It is the best anti-spyware freeware that I’ve found in a long time. It can be found here:

Last, I use CCleaner to clean all that extra junk (temp files, etc) from my hard disk. It’s here:

I hope I can be of use!
