Suggestion here for all routers: a Malware Blacklist

Known malware sites, by IP address, could be blocked.  I know we can manually add blacklisted IP addresses in most routers.  (I haven't even tried with my WNR3500L yet.)  However, these functions are usually far too limited both in list size and ease of adding to the list.  Many are limited to 20 to 50 addresses, when there are several hundred out there.  Also, adding to the list is usually a one at a time ordeal.  This would take decades with a list of hundreds of addresses. 

Even if all that is added is a way to paste a list into the router interface, that would be hugely helpful.
