Digital BW, The Print

sorry for the off topic post but i know there are a lot of smart
folks 
on this list who might be able to help. I need to check a possible
hard 
drive problem and want to optimize and check for virus. I have mac
os9 
and norton systemworks version 1. for some reason i can't boot up
from 
the norton disc while holding down the c key, which i understand is a 
must to use this utility. any ideas? sorry again for going off topic.
