Constant browser pop-ups (ad-type.google.com)

Hello!

We've had some issues with browser pop-ups in our house for a few months, and we weren't able to figure out what the issue was. This affects every laptop and android device in the house, though not constantly.

The issue is that, every once in a while when we click on a link or open a new tab/page, there is a browser redirect (on android) or popup (laptops) to the following address:
http://ad-type.google.com/sh.aspx?f=...d1b83443fbc54d
This then directs to http://www.tradeadexchange.com/ and then to some scary-looking page full of warnings of outdated Java or something and links which nobody is stupid enough to click on, thankfully.
E.g.
http://www.tradeadexchange.com/a/dis...28611445186973
(This is a warning page)Warning!

Lots of internet help pages we originally looked at indicated that it might be a router issue, but a total reset hasn't fixed the problem for more than a few minutes.

Any help would be greatly appreciated. I purchased a brand new laptop today and would like to actually enjoy using it...

Thanks so much!! :smile:
