Symantec AntiVirus Auto-Protect could not continue. Error Code 11

    Hi, after upgrading to Yosemite I'm unable to start Symantec Endpoint Protection v12.1.1000. I get this error message: 
    Symantec AntiVirus Auto-Protect could not continue.  Please run LiveUpdate or reinstall Symantec AntiVirus and restart. (Code: 11)

    What does code 11 mean?

    What's the exact version? Have you tried 12.1.5, which is the latest and first version to support Yosemite. See here:
