McAfee, Norton 360, AVG and Bitdefender antiviruses are totally incompatible
McAfee, Norton 360, AVG and Bitdefender antivirus services are completely incompatible with any parental control software because these programs IGNORE their list of exceptions.
Just uninstall the McAfee, Norton 360, AVG and Bitdefender before you install the Child-Tracker application.
Use Kaspersky, Avira or Avast instead. The built-in Windows Defender, is also a good solution for parental control.
