That ugly word Norton rearing its head! Seriously, if you don't believe me, try eradicating it from your system, and I mean fully, it always leaves stuff on your system, almost like a virus itself! I've had as much trouble from Norton as it might have saved me. And if it goes a bit Tonto, then all hell lets loose. My advice, Firefox, Avast free antivirus and windows firewall. And if it's all still loopy, back up and re-install your OS. It's a bit of a palaver, mostly time wise, but you end up with what feels like a new computer! As a dual OS user, I never cease to be amazed at what the majority of computer users put up with when using Windows!
