I can't get Live update to work and I keep getting the following message - AntiVirus auto-protect could not load the scan engine. Please run live-update to get the latest version. But when I run live update, it says it occurred today, about 25 minutes ago, but the Anti-Virus Auto protect won't turn on, just keep sending the same error. I have a newer mac laptop with Yosemite. Help would be appreciated. thnks
