HELP!! I’ve been getting a pop up ostensibly from Norton which says, “Your chrome browser is not protected. The Norton Chrome extensions are not enabled. Install these extensions to protect your device and your identity when you surf with Chrome.” Then there is an “Install now” button. I am concerned that this is not from Norton and that I would be opening my computer to all sorts of problems if I install this. Is it really something that Norton would send out and is it safe to install? THANKS!!
