Spam, banner ads, browser hijacking

I’ve installed this plugin because the features looked good. From day 1 they started displaying banner ads, even browser hijacking filters (when you don’t see ads, try to click on something but it will actually open up new tabs in your browser, displaying spam).

Tried contacting customer support, they reply to my question why they flooding my site with spam without my permission was a tutorial on how to remove their product from my plugins.

I think it says all.
