About 4 days ago I accidentally clicked on an ad on a site streaming live hockey games. Ever since then an ad service has taken over my browser. At the bottom of the browser at 720x90 ad will slide up and stay there. Also randomly when I click on the browser (Google Chrome) a new browser window will pop up in the back which has the address of thecdn.04stream.com/ext/pop.php which redirects to another URL showing an ad.
I have tried many anti virus, malware software and I can't get rid of it. I'm using Windows 7. HELP!
