I got a XPS desktop last year. Now McAfee "your subscription has expired pops up while I'm doing some extremely important activities." They take up 3/4 of the screen and I can't dismiss it; I have to restart the computer. This is outright evil. I don't want to see this thing again. But it keeps coming up. This has absolutely turned me off to Mcafee, and I'm considering brands other than Dell. Any way to disable this?
