This is also the purpose of using DNS management like Umbrella from OpenDNS, which has been serving me very well. It catches most malware sites, and I can add in my own whitelist, blacklists. I did get a bit overzealous and add a cdn once that caused a ruckus, but besides that, one by one blocking ad networks based on which ones generate the most traffic is not only keeping my bandwidth cleaner but makes parsing through dns logs much easier.
