Keep getting this interrupting intermittently but when doing so is very persistent. Have tried ALL suggested methods (Google articles, Adwcleaner, Junk Rem, oval Tool, AVGMalwarebytes, delete adnxs cookie etc.) and it seems to disappear although the tools don't say they have found anything untoward.
I think it is something to do with IE - system seems to think I have IE11 installed, other parts think IE9 (e.g. Trying to install IE11 again, which MS site says it is the right IE for Win 7 which I use but near end of install it says 'wrong version for your OS'! Oddly enough, adnxs is not interrupting my typing here but was 5 mins ago when typing to another forum. Odd.
I am using AOL braodband if that helps.
