CloudFlare collaborated with OpenDNS to launch a similar initiative.

Now, Google is doing its own bit by alerting the users affected with DNSChanger malware through their search result pages.

Users affected with DNSChanger would get a notification when they try to use the Google search engine.

Google spoke about this initiative:

Starting today we’re undertaking an effort to notify roughly half a million people whose computers or home routers are infected with a well-publicized form of malware known as DNSChanger. After successfully alerting a million users last summer to a different type of malware, we’ve replicated this method and have started showing warnings via a special message that will appear at the top of the Google search results page for users with affected devices.
