Computer protection????????

I’m building a computer. I’m spending a lot of money on it. I want to know ALL protection needed to keep my computer clean and healthy.

What is the best program for the following? (Preferably NOT free)

Anti-Virus
Anti-Spyware/Malware/Adware
Disk Defragmenter
Registry Cleaner
Disk Cleanup

And if I missed any other cleaning/health program, please specify!
And I don’t necessarily mean one program for all.

For some reason my computer is been freezing lately, wow is lagging like crazy and counter strike just froze after a while of playing. I tried many Registry cleaners, scan my computer for virus, spyware, malware.I have defrag my computer, update everything. I checked over heating and dust seems fine plus i put my fan at its fastest pace so it wont over heat. This started to happen like a week ago.
