Block those IPs that are obviously p4wned until they clean up their PCs?
Hi,
generally speaking 20 % of NXDOMAIN (or even more) is about normal

Blame Google Chrome and the like, they use it do detect DNS hijacking.
Aggressive use of DNSSEC-validated cache will help for signed zones but
there is no real 'solution' except fixing
