A family member was infected with a really slick mem based rootkit a few months back. they have a norton subscription. norton never caught it at any stage, so i had a convo with some techs. they tried to push that product on me. i was irritated that a service call about their products failure triggered a sale attempt and i cut it short. However, malware can now hide in routers and spread through networks once in. its not so much the network as an entrance point, but whats happening inside and whats calling out and when. having your router integrated with security, as well as monitoring could be pretty convenient for a lot of general users. i think its a good idea-as a product. That router is a part of a full norton av, though. its like pcmatic built into a router with some extra tools. so, you would have two full av products running against each other.
