I left my MBP on last night and this morning when I went on it, this box was in the lower left hand corner of the screen: As soon as I saw it, I tried to get to MacRumors but Safari would not load and neither would FireFox. I even tried to check my email by loading up Mail but it couldn't connect neither. A simple restart fixed the internet problem. I have never seen this Norton box appear before. I do have Norton Antivirus installed. I checked it out and saw that Vulnerability is active. So I would guess that that is what that box is. Norton did it's job. I would just like some insight on what has happened or nearly happened. Thanks.
