Explorer - the 'shell' that contains your desktop, windows etc
Navapw32 - Norton Antivirus
Rundll32 - allows a dll to run as a program (almost certainly required to let the game run)
Point32 - probably MS Intellipoint mouse driver
Systray - your System tray (clock, network monitor etc)
Rnaapp - the modem / dialup service
It is unlikely that any of these are causing the problem, and I would not recommend disabling any of them, except rnaapp if you are not playing online. Go for the patch as your first step.
