I just installed a new Windows 10 PC. In the past I would install Zone Alarm firewall and Norton AV software. I would like to simplify my system by installing only one Internet Security Package. I read the product description for Norton Security Deluxe (NSD) and it does not specifically state it contains a firewall. Interestingly it also doesn't mention that NSD does not support the Edge browser (that is until you get to fine print) which is concerning.
