I have opendns (uninvited) but not where you would expect, like in windows explorer, or add-on. It is somehow embedded in my own wifi hotspot (Lumia phone) from there it is blocking my desktop and other lumia phones, whilst on the wifi.
I believe I may have picked it up using the Lumia phone at a public wifi hotspot at Bankstown NSW.
This is not the first time, previous I had it on my android hotspot, that time I reset the operating system, I dont want to do same this time, yet.
Has anyone the same, and who work out how to it, Also other names are popping up, such as scansafe and cisco ( I believe cisco may own both opendns and scansafe )
