I, too, am having a big problem with Internet Security. It disappeared, I called and got tech support, uninstalled and reinstalled it. Then it worked for 10 minutes until I did the restart after installing FlashPlayer. Now it is gone again!?!? It put up a message saying, "ERROR-checking for a fix and had me restart to see if it could fix itself. Nope, it states the error is 8506, 422. I've been at this since midnight!! HELP, SOMEONE......
