Some users may experience an error when shutting down their computer where a Mac OS X info dialog appears saying that "VirusBarrier cancelled shutdown".
The most common cause of this error is if you have added VirusBarrier to your Login items under Mac OS X System Preferences/ Users and Groups (or Accounts). You should NOT add VirusBarrier to Login items. We have an article that discusses this here. If you delete VirusBarrier from your Login Items area, restart your computer, and still receive an error please contact our Support Team for additional assistance.
