After looking at my mail I was unable to turn my computer. I got a message the window in the middle of running a lengthy program. Thus I unplugged the computer. I am concerned that someone could be using my computer.
In the past I had the problem when I opened word and went on line. Doing a restore fixed it. I contacted McKafee and got no help.
