I tried to renew Mcafee protection but it wouldn't load. I bought Norton protection and installed it. Some time later I turned on the PC and Norton message of "high CPU use- system 32, spool/sv. For 3 days , it kept coming up and now saying more than one CPU is being used. I do not have a canon printer but do have Brothers MFC 7340. What can I do? Thanks BOBMONROE1 person got this answerI do too
