I have Norton 360 on 3 computers - desktop, laptop and net book. There are 2 users - me and my wife. On the desktop, I have no problem but when we switch user, my wife has all kinds of issues. She gets high CPU usage, Norton blocks several viruses, the computer starts running fast, and then it freezes up or works very slowly. I've run full system scans and power eraser 4 times each. Right now, she can't even open Norton when signed on under her name. We have Windows 7. Is there anything we can do short of reformatting or buying a new tower? Is there any way we can talk with an actual person?
