Back a couple of years ago when I first found this forum I read and read other's problems and learned a bit. Then suddenly one day I had problems and turned to Cyber Tech Help for assistance and my problems were solved. Since then I have kept a number of programs on my computer....run them frequently and keep them updated. During this time its nearly as if spyware, virus and other nasties were never developed. My point is simply this follow the advise you get here...be deligent in using what is suggested and the internet will be a much nicer place. Its only when I see a friend's computer who doesn't use any "protection" that I remember there were such things as pop ups. Thank you Cyber Tech Help - Webster
