I use Norton Internet Security 2011. When I go to the performance tab in the user interface, I get a transition that seems to be some kind of glitch. It is a random assortment of pixels that appera only for a seconf, while the PERFORMANCE interface loads. I have uninstalled and reinstalled with no success in fixing the problem. It does not really affect anything, but if there is a reason for it, I would like to fix this. I have posted some images to illustrate the exact circumstances.
