OpenDNS hijacks keywords that you type into the address bar and redirects those searches to their own search interfaces that pulls in Google results and their own ads.
This is really the only thing that I do not like about OpenDNS, is there a way to disable this behavior?
Note: if I disable the OpenDNS proxy it also seems to disable content filtering which is one of the main reasons I have OpenDNS enabled on my network. So that doesn't seem to be a good solution.
