ok. when that comes up, just put a check mark in the box and click ok and it wont appear the next time you reboot/restart.
If I were you, I would run msconfig cleanup
to get rid of all those invalid reg entries that you dont need any more. You will probably notice your system is a little faster since you dont have all those startup items any more. You saud they are checked again right? if so, go back and only leave checked your antivirus, click apply, but dont reboot yet, run msconfig cleanup, click select all, the click clean up selected, now reboot and all those entries will be gone.
