Mcafee security centre is the Graphical interface for the products but what the products are and what they do are detailed here
All depends on what you need...
Need one more advice. I have a home office Dell laptop with Vista 64 bit bought in 2009. McA came with the purchase which I renewed last year.
My current McA subscription expires on 17 November 2011 and I need to renew my subscription. The current subscription is not the McA is .
If I opt for total pritection today, will the subscription start today or from 17 Nov 2011?
If you are getting a new product you need to uninstall it using windows removal programs in control panel then run the MCPR tool
This is mentioned here
reboot and run
install from your new subscription.
