Microsoft Windows StartUp?

I have a 2005 Emachines computer with Microsoft Windows Media Center and it takes about five to ten minutes to startup. Once it has completed its startup theres about 25 programs under owner in the Processes section in the Task Manager. And I have found that my computer works better and faster when I remove almost all of these. I close all the programs but explorer.exe, CCAPP.EXE, and SymSCUI.exe. The question I would like to ask is, is it safe to remove these Programs from Startup or even close them with the Task Manager? Some of the programs I close include Spysweeper.exe, BigFix.exe, mcagent.exe, and other programs which might be antiviruses or useful to my computer. I would really appreciate any help. And in advance I would like to say thank you.
