You don't need any of those programs to speed up your computer. They can do more harm than good, sometimes turning services off that you didn't really want to turn off.
My friend and staff member here Artellos
wrote up a nice guide: Maintaining Your Machine
. Do everything it suggests and that's about it. It's all I do, and my computer stays nice and speedy (even my old laptop).
If you need help with the msconfig part of the guide, then let me know... I can help guide you through it. Finding out what startup is what, just research it similar to how you have learned to in GeekU. Don't ever turn off Anti-Virus, any malware "real time" protection, wireless cards, and/or on laptops keyboards, mousepads, etc. Disabling them from startup does just that, the program and service is 100% accessible whenever you want, just doesn't automatically start when the computer boots.
Hope that helps.
