Hearing you describe this had me envisioning the following shrink wrap product: buy "Secured home router" plug in cables turn on launch web browser captive portal configuration screen configuration goes through common steps, advanced options buttons for those who know what they're doing, one of which is an option for 1 month free software upgrade/virus/malware/firewall administration, 3/6/9/12 month subscription rates and sign-up process. Actual functionality is: firewall provides reasonable QoS parameters for a shared internet connection and prioritizing traffic in a manner that benefits user-interactive applications (HTTP(S) over p2p, etc.), dns blackhole for known malicious domain names, updating firewall rules for blocking known bad IPs (stolen abandoned blocks, etc.), captive portal style page hijacking for sites known for malicious content (with an ignore this warning button), software updates, configuration backup to a central server. The main issue I can think of is that the end user wants to feel like they're completely uninhibited on the internet. The problem is that to protect against most real threats, there's trade-offs and you'll have a 5-10% error rate for blocking traffic the user really wanted. This means that support would be a difficult cost to overcome, but I think a url on the system that resolves locally to the router to provide a "what problem are you having yes/no" style troubleshooter could help prevent a large number of complicated call ins. All in all, this sounds like a really interesting problem with two sales domains: target the consumers directly and target ISPs looking to have another value-add to their internet products.
