I just got a new computer. On my old computer I used Norton and I never got any notifications, but on my new computer my DIL put AVAST which is what she uses--recommended by her father who is a computer tech person. I have gotten several notifications like Cheryl pointed out the last few times I have been on the forum. I have don't go on any other sites and don't have a facebook, so I'm not a good person to use for a judge on whether it is happening elsewhere.
My life is much richer because I have friends like you.
