94 McAfee Internet Security Banning computer connections You can add, edit, and remove banned IP addresses in the Banned IPs pane. You can ban computers that are associated with unknown, suspicious, or distrusted IP addresses from connecting to your computer.

Make sure that you do not block important IP addresses, such as your DNS or DHCP server, or other ISP-related servers.
