I just noticed you've got a banner ad above Photos - that's not from HF either.
HF runs one banner top right, two hot boxes on the home page and one hot box on the music page.
Ouch, cheeky fuckers:
Counterflix changes your computer’s DNS servers to ones under their own control. This allows them to not only monitor what sites you are visiting, but to also replace requests from legitimate ad servers with their own ad servers.
These DNS servers are one of the main reasons that people find it difficult to disable Counterflix ads from displaying on their browser. This is because if you uninstall the Counterflix program, but do not disable their DNS servers, they will continue to hijack ads and display ones of their own choosing.
When your machine is infected with the Counterflix adware, other common symptoms include:
* Advertising banners are injected with the web pages that you are visiting.
* Random web page text is turned into hyperlinks.
* Browser popups appear which recommend fake updates or other software.
* Other unwanted adware programs might get installed without the user’s knowledge.
To make matters worse, you will also find that Counterflix will cause your computer to act more sluggish or for your web browser to freeze.
I wondered how a pop-up could hook into HF and not BBC, FB or Gmail and I think it must be google ads. That would give them common code to replace and given how prevalent google ads are, it would make good sense to go for the biggest.
