I suddenly noticed that my Windows Internet Security had been disabled. When I try to re-activate it, the options were unavailable to be changed...It had been grayed out, and I could not turn it back on. Is this related to Norton Antivirus or Spyware Search and Destroy Program on my computer. I have had Norton for a while, and it has never disabled my firewall. So, I was confused why this was the case, and what I needed to do to get the firewall enabled? Your help would be greatly appreciated! Thanks!
