This one looks pretty good.
Now you need to run HJT again and place checkmarks next to the following entries;
O20 - Winlogon Notify: NavLogon - C:\WINDOWS\

O23 - Service: Symantec Password Validation (ccPwdSvc) - Unknown owner - C:\Program Files\Common Files\Symantec Shared\ccPwdSvc.exe (file missing)

O23 - Service: Symantec Settings Manager (ccSetMgr) - Unknown owner - C:\Program Files\Common Files\Symantec Shared\ccSetMgr.exe (file missing)

Once you have placed the checkmarks then click the Fix Checked button.
Exit HJT
Reboot.
Now you do have some unnecessary programs running at start up that can easily be run manually, if you like I can give you a list on which ones to disable. This should speed the computer.
