Hi Just switched to my first Mac and have a couple of simple questions. Currently I use a Mac mini 2012 model with an old D-Link DSL-2640T ADSL Router. Am I better off using the hardware firewall in the router or the software firewall in Mac OS X? I have installed Avast AV but will most likely uninstall that or turn off real-time protection as I can't see myself needing it. Thanks in advance.
