I honestly don't know what to do. I'm not that computer savvy. For the past couple of months there's has been like these things that pop up on my computer, and sometimes when I am playing on my computer it will randomly go back to the main screen, and stuff that I think a virus would do. For the past few weeks my computer has had these green and red dots that will sporadically move and when I don't move my mouse sometimes the dots won't move. I don't know what to do or what's wrong with my computer but I need help!
