Problems connecting to the App Store since installing McAfee Live Safe
We have started having problems connecting to the App Store and to the internet. The most recent software we downloaded was McAfee Life Safe. The problem is intermittent. We can reboot and get into either of these for awhile but then it locks down again. We are on a Mac Air with the latest version of Mavericks (just got the comptuer a week ago).
Any thoughts would be appreciated.
