A weird adware is popping up every time I open a .com website and shows ad or redirects the page.
In chrome, I'm not even able to open an ordinary .com page because it immediately redirects to somewhere else.
I've reset Firefox, even purged and reinstalled it but the problem's not solved.
This is one screenshot of mine, you see the adware at bottom-right corner.
I'm using Kubuntu 14.04 with firefox 36.
