I use Comcast and McAfee AV, firewall etc comes free. I'm not planning to use it but I have a few questions: 1) I read their firewall is only for incoming, is this true? No outgoing protection, like Windows Firewall? 2) I know the AV is good in general, but how is it with spyware/adware? Does it include detection? 3) Does the AV update itself? My sis has it installed and I couldn't find a way to update it.
