I'm not gonna try to reset my router just yet, but I have unregistered everything I can. There's still one left with YouTube that has no option whatsoever to remove it.
Since these are just in my appdata folder, how would this change anything? If these are put in there just based on what sites you have gone to, and I still got the popup notifications after only visiting three websites ( the AVG site, Google search and the Chrome download site ), how would this be the issue? I'm not trying to say it's not, I'm just wondering.
