I just recently upgraded my Mac to OS X 10.10.2, and frankly have been having a time getting everything smoothed back out after having to upgrade a lot of my software. Right about the time I started the upgrade on my machine, my Norton AntiVirus subscription came up for renewal, and I was told at that time that it would no longer be available to me to update, that I would have to start using Norton Internet Security instead. I'd really like to hear from anyone who could help me as to whether or not I should expect to have any particular problems with the installation and what to do about it, and also whether or not I need to do an "uninstall" of my current Norton AntiVirus before I install the new app, and if so, any tips on that would be very helpful. Thanks for any help anyone can give!
