We have Norton but it doesn't have a little icon in the right hand corner of the desktop, so I don't know if it just runs all the time or what. And I don't know if it is updated but I'm going to check on that and get it running.

I would not be surprised if I had a virus. Over the last couple of weeks the computer will just randomly pop up with the infamous blue crash screen, but you can't read anything it says. The characters are like scrambled/blurred, and there's nothing you can do but pull the plug,
