There is a "popup" type window, that suddenly appeared on my Windows 7 laptop one day. Its a rectangular window, with few lines of "random" sentences, that don't make any sense whatsoever. Like, "Some message", "Some text", "Subscribe now", "EVAL TEXTTTTTTT". There is an "x" button with the label "Hide this message", I clicked on it and it won't go away. Not very good with computers so please slow it down for me. I also did a full scan check, and it still didn't destroy it. So i don't know what to do, quite frankly.
