Fix this one:
O4 - HKLM..\Run: [ScanRegistry] C:\W

These ones are not needed for the system to work, you can safely remove them if you wish:
O4 - HKLM..\Run: [Disc Detector] C:\Program Files\Creative\ShareDLL\CtNotify.exe
O4 - HKLM..\Run: [CTStartup] C:\Program Files\Creative\Splash Screen\CTEaxSpl.EXE /run
O4 - HKLM..\Run: [WinampAgent] C:\Program Files\Winamp\winampa.exe
O4 - HKCU..\Run: [MSMSGS] “C:\Program Files\Messenger\msmsgs.exe” /background
