Hello guys, I'm having a banner problem on my chrome. It's the same type of banner on different sites. The screenshot is as follows: http://s15.postimg.org/6m8sv9z97/Screen_Shot_2014_05_16_at_23_51_09.png I have to click on the top right corner, black area, to close it. Is it some kind of a virus or malware or anything like that ? How can I avoid it ? Thanks much.
