Installing McAfee on my computer. After restarting a system, this message appears in the Virus & threat protection page in Windows Defender Security Center. Threat Prevention tries to send the Endpoint Security security status to the Security Center service. This fails because the Security Center service is not in a running state immediately after a restart. After about two minutes, when the Security Center service is in a running state, Threat Prevention successfully sends the security status and the message no longer appears. Help me!
