I need help finding source of adware

I recently, and I'll admit stupidly, downloaded a file off of piratebay and now I'm plagued with annoying adware. I downloaded the file and entered my password without thinking and immediatly regretted it. This adware is causing popup banners on the sides and bottom of my screen that I cannot close, only hide. It also is highlighting random words with more pop ups attached and on some websites, wikipedia for example, every time I click somewhere for the first time on a new screen another pop up appears and opens a new tab/window. I'll attach a screen shot to help give an idea of what I mean. I have no weird extensions as far as I can tell, I've ran a scan and nothing turned up, I've deleted all cookies, and I deleted the plug in the was downloaded. My only guess is that something other than the file I meant to download went unnoticed and now its giving me ****. Any help would be GREATLY appriciated. Also I know its not DivX or genieo.
