I would go with your disc as the software is upgraded much more slowly when it comes via 3rd parties. If you choose that route, uninstall the old one, and then use the MCPR cleanup tool under Useful Links above, reboot and install using the online option if offered during the installation. (It creates an online account).
I don't understand what is "MCPR cleanup tool under Useful Links above?"
I didn't see that at the top of the page.
I can't thank you enough for your help.
I uninstalled Dell's version and installed Total Protection 2011 - mainly because of your prompt replies to my posts.
I am so glad to know of a place where I can get help if it is needed.
I am not sure how to mark this as complete.
You're very welcome and I've marked the thread as solved. All the best ;-)
