Use McAfee's Firewall settings to allow Internet access for certain programs.

McAfee products that have a firewall -- such as McAfee AntiVirus Plus and McAfee Total Protection -- include settings that partially or completely remove the Internet access restriction for programs. Although blocking Internet access to many programs can prevent computer infections, some programs -- such as instant messengers -- need a connection to the Internet in order to function. The option to unblock a program’s Internet access restriction is located in the "Internet Connections for Programs" section of your McAfee software’s Firewall settings.

Launch your McAfee software, and then click "View Firewall and Anti-Spam Settings" in the "Web and Email Protection" box.

Select "Firewall" to open the Firewall window.

Select "Internet Connections for Programs" to display the Program Permissions list, and then scroll down the list until you find the program you want to unblock.

Select the program, and then click the "Edit" button.

Click the "Access" drop-down box, and then select the appropriate access permission. Select "Full" to allow the program to send and receive data; select "Outgoing" to only allow the program to send data.

Click the "Send" button to activate the program's new Internet access permission.


  • If a program you want to manage in McAfee is not in the Program Permissions list, you can manually add it to the list. Open the Firewall window, select "Internet Connections for Programs," click the "Add" button, and then click "Browse." Navigate to and select the program you want to add, and then click the "Open" button. Click the "Access" drop-down box, select the access permission type, and then click the "Save" button to add the program.
