Since I am a novice at this,I always try to see what I can see.One that stood out to me was
O4 - HKLM\..\Run: [REGSHAVE] C:\Program Files\REGSHAVE\REGSHAVE.EXE /AUTORUN
as well as
O4 - HKLM\..\Run: [QuickTime Task] "C:\Program Files\QuickTime\qttask.exe" -atboottime
and
O4 - HKCU\..\Run: [Rainlendar2] C:\Program Files\Rainlendar2\Rainlendar2.exe

I'm sure that Judy will find a few others.I do know that some programs should not be allowed to run at startup,and the people here will be able to advise on the programs to set up your system to optimum running performance.
