Getting Strange Number Of Processes Upon Startup?

I recently downloaded PC Tool's Spyware Doctor and ever since then my memory usage went from 400 to 600 while in idle.So to cut down on memory I carefully disabled some more Processors and Start-Up programs I then went about and checked the "Adjust computer for best performance" and adjusted the Processor Scheduling to "Adjust for best performance of Background Services" It was only after those two changes that I relized when I opened Task Manager and clicked the processors tab there were only 8 processors there: firefox.exe, explorer.exe, taskmgr.exe ctfmon.exe, winlogon.exe, csrss.exe, sprtcmd.exe, pctsTray.exe.
