Okay so over the past few days these boxes keep popping up on my screen and disappearing. They pop up for a split second and then go away. It's kind of creepy because I don't know if someone has hacked into my computer, or if something is wrong, or something like that. They don't stay up long enough for me to read what they say. Any answers would be greatly appreciated. They look kind of like the error boxes that pop up in the middle of your screen if that helps any, but like I said they disappear.
