I have an HP computer with Vista, Comcast as the ISP, and McAfee (I think it was provided by Comcast).
A new problem has popped up just recently. Every few minutes, I am interrupted when the black and red McAfee flash-screen is flashed on top of whatever I am working on. That is followed by a tan-colored screen called “Comcast Security - - - powered by McAfee”. (This is the same screen that comes up if I click on the McAfee shortcut on the Desk Top.) That screen changes its contents once before it quits. The coming of these screens has nothing to do with my pushing keys. They come even if my hands are not near the keyboard and if I am not on line with Comcast.
These screens flash on for only a fraction of a second – not long enough to read what they say. But they disrupt my train of thought and, if I am typing, can cause errors in my writing. I checked my McAfee and security settings and they seemed correct. If you can suggest a way to stop this, I would appreciate it. The screens have flashed on about six times while I was writing this.
