When you have installed the McAfee Security Suite in your system it will control your Firewall Settings in windows. In some instances I have encountered File and Printer sharing problems due to active firewall settings. In these post I'll teach how to Disable it by doing several steps below.
To Disable McAfee Security Suite Firewall:
1. Open the McAfee Security Suite Center
2. In the upper right corner click the Navigation menu below the Home.
3. In the Navigation Center go to Features column and click the Firewall menu
4. A new window will open,click the Turn Off button to Disable the Firewall settings.
