I haven't noticed any shutdown speed difference, but I am running Windows 8.1.1 on all of my machines. Was this a Win7 issue? Also, the remoting in aspect is likely fixed under Firewall Rules. Norton has a pretty aggressive firewall, and you will likely need to disable. Do you use IPv6 via IPSEC from work? Norton by default blocks any 'Tunneling' with it's FW as a security precaution, but a single checkmark will fix that. Norton also blocks IPv6 depending on how it is used, because IPv6 can be a security risk, especially if it is using Teredo. That also can be disabled under FW rules. My only issue with Norton 2015 so far is that Download Insight doesn't play well with Opera. I consider Insight to be one of the more powerful aspects of Norton, and having it not play right with Opera means I need to abandon Opera. Not a big deal, I don't really like the direction Opera has been going. So far that's been the only thing I noted, and I find it very light, and using only minuscule resources.
