I need to uninstall Mcafee security centre from my Inspiron 531 so i can install Norton Security (Our other PC is running it). There seem to be a gazillion 'methods' of removing the Mcafee from Mcafee itself, Dell and people with far more PC savvy than me. So, I haven't registered the Mcafee yet should I do this before uninstall or after? Should I follow the Mcafee version with their little program (MCPR.exe) or the Dell one? How do you switch off the firewall and AV programs??  Apart from that, no real questions!

Thanks in advance
